Just got back from a two day camping trip and it was entertaining to say the least. Synthetic Air is ahead with the rv'ers, but the tractor bunch is still lagging behind. There were a group of S.I.N. (synthetic is nice) members trying to convert the non-sinners. Converts to sin seem to be somewhat fanatical in their approach and seemed to party loud and hard.
Then there were the greenies with their natural air. They also had fruit flavored air. They seemed to attract the bees and flies more than the other campers. A big honkin, motor home showed up at the camp ground. He sneered at the common folk using PA (plain air) as he used imported air, which comes from the first exhaled breath of newborn Siberian Yaks. The most fun to watch was the ole boy that put helium in his tires. The trailer was floating about a foot off the ground but was soon back on terra firma. The kids in the camp ground would sneak up to the trailer and release the helium and breath it in so they could talk like chipmunks. Leaving the camp ground I heard some blue air as a sinner lost the hose on his black water tank about half way through the process. I really don't think I would want to put blue air in my tractor tires, If you ever had a flat you would get a cussing at the same time. Just some musings of an old geezer who might give sin a try.
