While I agree with the general sentiment of the OP, I've been a victim of the reverse.

I was fishing a pond near the side of the road just off the Mississippi River in Savannah, IL, while waiting for my bass tournament partner to show up with his boat. My pickup was parked on the shoulder. I was casting and minding my own business, when I felt a stream of water hit me aside my head. I turned to see a group of roadies cruising past on their high-priced machines, giggling like school girls.

I suppose they thought they were getting back at all of the crackers who had ever taunted them. Obviously they didn't realize that I was also a roadie, just not on that day. Had half a mind to hop in the truck, tear after them, and let them know this key point, but you can't argue with idiots. And sometimes, the idiot is the cyclist.
