[Yosemitest]

I did 3 and a half years at March AFB, and I've been to Yosemite a couple of times.
It's one of the most beautiful National Parks that I've seen, and the first time was during its first snow fall of that year.
So my pen name comes from that vacation and my air traffic controller's operating initials.

OK gotcha...I always get “March AFB” (now ARB I guess) and former George AFB (now closed) mixed up! March is the one near Riverside I reckon.
