Couple women here in Tucson riding a tandem got a bit tired of cars sort of a few cars slowing down and patting the rear rider on her rear.
Great solution: she started wearing a holdstered pistol on her left hip (legal in AZ).
On our tandem been hit by several small objects.
On my single, been punched out by a motorcyclist.
Had stuff thrown at me from passenger in a passing truck. Caught up with him at traffic light, took a big swallow of water and spit it thru the open window in his face. They tried running me down and chasing me in their truck; made several quick turns and a couple U-turn to get 'em off my tail.
Several other incidents, but too many to list.
