I threw together a portable misting system this weekend with ideas stolen from our Indio predecessors... http://www.coachella.com/forum/showt...=mister+system
Mysting system from Home Depot about $15... http://www.homedepot.com/h_d1/N-5yc1...&storeId=10051
Water jug weed sprayer from HD.. about $17.
I cut off the hose bib conection from the mister then warmed up the tubing with a Bic lighter and pushed it over the wand stem of the sprayer. Then i used a zip tie to lock it on (which i will switch to a tube clamp).
Filled the jug about half way and pumped it up about 40 pumps. The mister worked great for about 25min without pumping again untill the water ran out. I would say after this trial run, the system is a good portable system for less than $30.
