And learn to lean. When you've never had to deal with leaning, it
can easily come as a surprise. Most of my training was/is in Colorado.
When I went to Phoenix for a few weeks on business, I took some lessons.
I immediately reached for the mixture to lean and was told "we don't
need to do that here". Hm.

One of these days I'll get to fly at sea level and find out just how
good my 180 hp aircraft flies...
