But you don't have cacti and rattle snakes to worry about!

You got that right! Where I fly the airfield is 128 ft. ASL, we spend a lot
of time at or below ridge heights of 4000-6000 feet ASL and to go above
12,500 you need permission from ATC - which is seldom granted. The cockpit
is usually a comfortable shirtsleeve temperature - except during the summer
on a day with weak lift where you end up sweating buckets as you scratch
away at low speed below 3000 for the whole flight.
