Thankfully I haven't seen any yet around here in my part of Louisiana. Don't see many around here even though I live out in a fairly rural area. Did have a bit of a tussle with an alligator snapping turtle last summer, though. He was in the road by my house and we didn't want to hit him, so I got out to move him before I realized what he was. I walked up and he hissed and snapped, so finally I chased him out if the road with a stick. I wanted to just get back in and hit him after he tried coming after me, but my friend who was driving refused so I got to figure out how to get that mean sucker to move. Both myself and the snapper made it out unscathed.
