Shotgun: If you are over 100-150 yards away. No big deal.
Rifle: Another story.

Basically hunters are usually very aware of their surroundings and set up so their shot will not affect anyone. Hunting is big here and anymore I don't even think about it when I hear a gun shot, especially in duck season. Sounds like a war going on. Steel shot doesn't go very far.

Now if I were in the city, I'd be pedaling very fast...
