I used to wave...not so much anymore. But if someone else waves I'll wave back.
Some of the cruisers I'd pass and wave at would give me the "I'm too much of a bad ass to wave at you" look. Funny when the last guy in a line of them, or their pillion rider would sheepishly give me a wave...almost like they were thinking, "I hope the rest of the group doesn't see me doing this".
Nice video Red!
