Motorcyclists wave to each other. Depending on where you live (and if you ride a
motorcycle or not) you may not have noticed this. But I make it a point to
wave to every
rider I see, and they wave back.
It's a lovely gesture. I may not like Harleys, and Rich Urban Bikers get on my nerves; Squids annoy me and I don't much care for the Honda Goldwing style of riding, but I wave to 'em all, because they're out riding, too.
They get wet when it rains, and they get dirt and grit in their eyes and mouth when the wind shifts on a dusty New Mexico spring day; they dread snow just like I do, and they look forward to summer just like me.
It's a pretty cool club to be in, and all you gotta do is ride something with two wheels.
