Not to highjack the thread about heat, I figured I'd start this one. Obviously everyone who has a cool shirt loves them but what about the rest of the weekend? I can't afford a nice air conditioned motorhome, so I bought a $50 Walmart 9x9 shade thingy. What I would like to have though is some kind of misting system but am not ready to shell out the big bucks for the already set up systems. The hoses and nozzles are fairly cheap to get but the water tank and pump seem to be the higher cost items in the kits.
What kind of DIY misting system have you come up with?
