It is warming up here in Southeast Texas and the critters are coming out! I drilled 3 - 1" holes in the side of my smokehouse 4" above the floor for ventilation. Too my surprise I opened the door and there was a snake inside. If I wouldn't have screamed like a young girl and attempted to outrun the stuff attempting to fill up my pants, I would have got a picture. Anyway the point to the story is be careful. I will now be putting some screen mesh over those holes.
