I agree with the pet peeve of cords and hoses, I have somewhere around 45 electrical outlets in my 24x30 garage, located at 48 inches and about 72 inches above the floor level. Excessive? Maybe, but I always hated having to hunt for a plug and have an extension cord running across the floor. I only have one air hose reel, I try to use cordless power tools as much as possible, but I do have at least 150' of air hose when I need it.
