I think everyone who is an avid wingshooter has been peppered on occasion.
I've only been peppered from a distance, and i only did it once to someone else myself. it was during quail season last year, I was actually shooting a cottontail that was sprinting up a hilll. Littie did I know that my buddy was on the other side of said hill. I hit the cottontail, but some of the shot peppered my friend on the other side. Oops. :) Since you're from AZ, you might even know the area - it was in the high desert between Jakes Corner and Punkin Center?
What part of AZ are you in? I live in Phoenix - unfortnately only got out a few times this season, but I did manage to take the limit in doves once.
