Would it be really, really gross - guts spraying into your face
I do not believe this would happen. But you might get a pissed off squirrel tossed onto your leg.
I usualy just hop over them, even on my road bike.
The biggest problem we have out here are rattle snakes. On a good day I will have to swerve or hop over at least 3 or 4 during the course of a ride. Now that it is cooling down they should not be around so much.
