Are men bike snobs?

[zoom-zoom]

I've seen motorcyclists nod and wave at each other, but don't think I've seen one respond to a bicyclists. (And no, it was not one of the Gold Wing people this guy was on a Harley and decked out in leathers).

I've had several motorcyclists wave and/or nod in my direction. It always has an air of "I see that you are on 2 wheels, too. Cool."
