Wow great idea! It sounds like the peg board will be pretty ideal! The only downsides for me is that I am using reptiearth sub and I might need to mist my setup. But yeah if it starts looking ratty I can just toss it. I found a bunch of perches that are meant to attach to bird cages that would be ideal for a snake but I had no way to mount them without drilling holes, which I prefer not to do. But the pegboard would allow me to attach and rearrange any time! I think my old school egg crate and burlap construction method would hold up better to the humidity but working with egg crate is a pain.
