I almost hit one with my knee this past summer, does that count?
I was riding a local road at the base of the foothills, came around a tight corner with my knee on the ground, and there was Mr. Turtle in the middle of my lane. I about crapped my pants! All I was thinking "Don't hit that thing with your front tire". Changed my line and lifted my leg so Mr. Turtle could live another day.
I read the story in my local paper and know of people who go after rabbits, tree rats, and just about anything they can make road kill with 44" tires. I do live in the south. Roadkill stew!
