A couple of days ago, I probably should have been bitten. I was working a bank of a family-owned pond and was checking for "dangerous things" in the weeds with my boot like an idiot. Kicked a fairly large green snake lightly in the head. Some sort of generic rat snake variety I'm sure, but can't positively identify as I bailed pretty quick. Definitely non-poisonous though, as I doubt that no venomous snakes in TN are bright green. Unless somebody has introduced green mambas or boomslangs without my knowledge...
Nonetheless, this should be proof that snakes aren't likely to strike unless they have very good reason, and even then they probably won't. Well, I dunno about the cobras and other elapid species that Rad might be subjected to. But I have put myself in a position to get bitten by virtually every snake species native to TN, and it ain't happened yet (knocking very deliberately on wood)...
