Ruffner Mountain Nature Center, located near Birmingham, Alabama, does allow letterboxing, but you must get permission to plant the letterbox first.

The contact person at Ruffner Mountain is Marty Schulman. He is the only Nature Center employee that handles letterboxing and geocaching. He will require you to show him the box and its contents for approval, and then he will go out on the trails with you to approve the actual location where the box is to be hidden. A good idea would be to find the spot where you want to hide your box and make notes on how to find it before you meet with Marty at the Nature Center.
