I always wave or hit the lights when I see H2's... most of the time, I get a favorable response, too!
The H3's are in their own world here, or so I have found -- rarely do they respond. Maybe they are just in shock that I am waving at them!
My husband asked one of the first times he was with me when I signaled another H2... he asked if that was some sort of a "creed" amongst Hummer owners!
