I'm fortunate to work in pro shop w/ an indoor range. Nice and cool in there, but I recognize those 20 yard paper shots aren't really enough to do it. I just utilize the cooler mornings and late evenings to shoot, and shade of course. But somedays, it's just TOO DANG HOT and I don't shoot those days unless it's indoors. Shooting w/ sweat running down my back, in my eyes, and the bugs swarming is just no fun.
