A LOT of bench space and pegboard for hanging tools. One curious thing
about
my hangar. I have an overhead light. When I raise the door, it vibrates the
hangar and the light goes OUT!!! It comes on by itself later on. It is not
an incadescent light, but it is not a long tube flourescent either. Looks
more like a streetlight. Why would it do this?

Based on the info you provided ... here's my wild guess: you might have a
mercury vapor or metal halide lamp.

actually, that contribution to the list was made by
Doug (I think).
