Sometimes I wave, sometimes I don't, like when I'm dying like an animal on the side of the road
in the heat.
There are a lot of riders here, and some very serious types who generally don't wave, that's okay
they're training.
I have yet to be stopped on the side of the road for any reason and had another rider or group
not ask me if everything was okay, or if I needed help etc.
I always ask if everything is okay when I see a rider on the side of the road, I do that when I'm
driving too, carry a pump in the car most of the time and tools.
