The term "redneck" originates from the fact that we are generally white trash with blue collar jobs which require us to work outside, or we happen to hunt, fish, and four-wheel, enough to have essentially a perpetual sunburn. My dad has that problem. He's got a permanent sunburn in a "v" on his chest from keeping the top bottons unbottoned on his shirt when we went hiking one time. Never went away.
But we rednecks also wear mullets a lot. Short in front, long in back, covering our neck. I don't know about ya'll, but I've never gotten a sunburn through my mullet. So the literal use of the term doesn't fit. Ha!
In fact, I am two shades more tan than dracula. I don't know why. My dad burns a beet red very quickly, and my mom tans deep as can be. I don't burn or tan very much.
Don't get me wrong, both have happened, but it takes about twice as much sun exposure as most white folk, and the burn or tan fades very quickly. I met several people on the Dunes that had burnd more through SPF 15 in one day than I did in three, no sunscreen required. I'm pretty sure this is not a good thing. My dad burned through SPF 70.
I know that a sunburn happens when the UV rays have damaged cells. It's actually a mild, topical radiation burn. Tan happens when cells produce a chemical, melatonin, that helps block those rays. So if I don't burn or tan much, it either means that my cells aren't affected by the radiation as much as most people's would be, or they just don't react properly. As far as I know, I've done the kind of damage that UV can cause, but without the redness and inflammation reaction that leads to healing. Or maybe my skin just doesn't overreact. But when I do actually get a sunburn, which only happens from long periods of very intense exposure, even a mildly red one itches and burns like hell. Think poison ivy with a saltwater loofah chaser. That probably isn't good, either. But in any case, this is knida freaking me out. Anybody else got this problem?

1/1000 of a mile in 30 seconds
Sandboarding worked both better and worse than I expected. For a prototype made of skates, a shelf, and a couple of chunks of plywood, it exceeded expectations. I was pretty much the only one on the sand capable of going downhill for a distance. Trouble is, that trip downhill was always slower than just walking, and turning was impossible. I knew that sand had a higher friction coefficient than snow, but I didn't fully appreciate the difference.
I have come away from this experiment with many lessons and ideas for improvements in my design. For one thing, I would make the board much lighter. It was a bitch to carry until we fashioned a shoulder strap system. Lighter would also mean that there would be about 20 pounds less weight on the board/sand interface, meaning less friction.
The board needs to be much bigger, in fact. Preliminary calculations have shown that I would need 11 square feet of contact to get some serious speed, at least using wood. We can't make the board any longer, since then it won't fit in the trunk, so it needs to be wider. Almost three feet wide. That's not going to cut it, but it would be worth a try.
Also, sand is extremely abrasive. You knew that. I just spent four days sanding my sandboard with 80-grit the hard way, and it removed between three and five coats of latex paint (I know how many times we painted that shelf). This reinforces my descision not to use an actual snowboard, even the P.O.S. that I have, since it would have ruined it, and the odds of finding another $25 P.O.S. are slim to none. I want that board for snow. I was going to go to Wal-Mart and get some Teflon kitchen spray for the board, but further thought revealed that if steel spatulas scrape off non-stick on pans, the sand would make short work of the whole can of teflon spray. That idea was scrapped.
Steel plate seems like the logical idea, since it can be thin and strong, but the weight kinda worries me. It was suggested that we could attach a steel plate to the bottom of the wooden board and see what happens.
We knew that whatever we put on the bottom would get scratched to hell, so we had to come up with something durable and slippery. The possibility of custom-pouring a glass bottom onto a rigid steel board was tossed around. That would be hella fun, but I'm not sure it's a good idea. Our neighbors chuck enough empty bottles onto our lawn to more than make up for the glass requirement, though! If only they knew that I've been making glass nick-knacks out of them and selling 'em for a pretty penny, maybe they'd stop doing it. Nah!
Since there is always at least a 10mph prevailing wind at the Dunes, often faster, and quite a bit of flat land, I do believe that it would be an excellent place to kiteboard. That's basically kitesurfing, only on land in motorcycle gear. Falling sucks, and will rip you up! I'm tossing around the idea of putting footstraps (not boots, straps) on a board and attaching large tires. Balloon tires. The Sand Dunes Visitor Center has two sand wheelchairs. Brilliant inventions. They have huge soft rubber tires, easily two feet in diameter and eight inches across. Turns out they only take two to four pounds of pressure, and that they had to get a special pressure guage in order to be able to check them, which they got from an ATV supply store. I'm pretty sure that ATVs use inner tubes, and if so, I would be using an inner tube as the outer tires on my kiteboard. I'm a bit worried about puncture-resistance, though. Does anybody have experience on the subject? In fact, does anybody have experience with handling a power kite, or own a mountain board?
Even as it is, the sandboard was a people magnet. There's something about being both brilliant and batshit crazy that just draws people and questions. I love talking to people, even fielding questions about my various schemes. Really, don't avoid someone who's doing something that probably means they're a few grains short of a sandpile, ask 'em about it! Hot rodders may build cars because they love building cars, or driving their dream car, but we do love it when the person at the other gas pump strikes up a conversation. Whenever you invent something cool, it's nice to know you're not the only one who thinks it's cool. Or even just weird.
