A word of caution to anyone in a humid climate... evaporative coolers don't
work worth a tinker's damn when it's humid. Nobody in Toronto even knows
what one is, they don't even bother to try to sell them here. I moved here
from Salt Lake City (and even lived in the general Moab vicinity for a
couple of summers), so I've experienced both "dry heat" (here, drink a glass
of sand) and humidity (here, breathe a swamp). I can definitely vouch that
the evaporative cooler I used to spend so much time in front of would just
make things worse in the humidity.
I'll bet this trick works great in Vegas, though.
