If I understand correctly, some guy called him saying all the critters in his neighborhood are gone and there's snake tracks leading to his camper. The OP is going to try and catch the snake, but isn't quite sure what it is, correct? Are you in Florida or Delaware?

I don't know how cold Delaware is this time of year, but Wisconsin is hitting the freezing point this week during nights, so if there is a big snake around the area, he/she is going to be looking for heat if its getting cold out east. Look for heated garages, around dryer vents, etc.

Good luck!
