...by a seldom mentioned hazard of riding: bird shit!
A flock of god knows what flew by. 3 on my tank; 3 on me: 1 on my jacket, 2 on my visor; 3 on my rear seat; and 3 on my rear fender. Precision carpet bombing at its finest.
I'm glad I had my visor down. If any of that crap got in my eyes I might have been blinded.
