Rural parts Yards down here, you can never tell what you'll find living in a car. If I have to wade in weeds, makes me nervous.
Racoons are usually OK, because they chase the rats away. They can gnaw on things, but rat poop is the worst, and they eat everything, I think, so racoons, no problem.
Snakes should eat rats too. Theoretically, at least. So, I guess I shouldnt let them bother me. But they do....if I see one, I head the other way.
And you dont want to be out where there are skunks roaming around. I have never been hit by one, knock wood, but I think that would be the worst.
