I work near the North end of the runway at March ARB. Get an airshow regularly. One neat thing I've noticed is my ability to identify the usual planes by sound.
C-141's, KC-135's or KC-10's, C-130's, F-16's are most common. C-17's or C-5's less often.
We also have a local contingient of the CAF flying a formation of four T-6's. They practice 1x per week at least.
I usually go look now only when something sounds different.
The real fun happens when there is an airshow at the base. The fly-in of planes all week makes work impossible.
