No, I don't have pictures, sorry. Built it as a kid and didn't think to take any at the time; sorry. As to the drop off, yes, they could find their way out and how often they would, wellllll...I really couldn't say, lol! I have zero experience with bullsnakes and their habitat, as the animals in my neck of the woods are primarily corn snakes, some rat snakes, copperheads and in the southern part of the state Easter Timber Rattlesnakes.

I'll see if I can figure out how to upload an image and show you a sketch of what I'm talking about, as the original trap is long since gone.
