I don't want to be getting comments saying it's not a bison tube, i never said all of the RD series would be bison tubes.
Small windchester container about ten feet in a tree. Luckily, the tree has footholds, but still be careful. After you have found all RD sereis caches, you have found the challenge cache...the challenge is to find all the RD series caches. Happy Caching!!
