I've flown in and out of KSVC (Silver City, NM) during the July. It's only at 5440 feet, but it took a lot of extra care at summer DAs. Landings were a matter of flying onto the runway; there was no flare and I applied ten degrees of flaps only after crossing the numbers. Takeoffs required resisting the temptation to pull back on the yoke; waiting until there was sufficient airspeed to let the airplane lift off in a level attitude. Otherwise, the airplane would wobble along in ground effect until it reached the site of the crash.
As much as I like flying a 150, I think I'd be looking at an older 172 or some other aircraft if I lived at your altitude.
I’ll be the second (of many I will predict) to recommend you look at other airplanes if you are flying out of an airport with a 10,000 foot density altitude. The 150 is an awesome plane but it’s rate of climb isn’t its strongest suit. Unless of course you can score one with a 150hp conversion.
