I don't use a hide either, it's really not necessary if you use an enclosed rack system (only open at the front) because basically the entire tub is a hide. If they need to feel more secure they burrow under the newspaper.

For a more naturalistic setting, you can find a plastic storage container with a secure snap on lid that the snake will fit inside, cut an entrance hole in the side and hot glue rocks or wood chips or bark slabs to the outside.
