There's 1 at the local irrigation store just outside the door, so when it's hot walking in or out you get "misted"  even a couple minutes standing there even in direct sun, the mister's do help.  (mister's are pretty popular in places like Az. Tx. etc.. so I've been told. I'm not about to go down there for a personal inspection,,, krap it's 100 ++ down there !)

I bet the cows are liking the sprinklers running more than not having sprinklers running ??
