Here's my idea to make what I was going to have as one enclosure I'm going to make 2 but with a center wall that's plexiglass and remocable easily. Well Here's the pics... That's just a basic idea of what I'm going to do with larger rocks and it's all going to be removable so I can move this huge thing fairly easily. Here's lower pics of the design... it's going to be supported a lot better but this was just a way for me to completely visualize my design. The cave is going to be under the Pond and mostly closed off except for the Front corner. This is going to be for 2 Argentine Boas of mine that I'm hopefully going to breed. The top shelf is going to stick out a little further and I'm going to have a branch in both of them so they can get closer to the Heat bulb.
