Check out Cam Lock Boxes.... Cam Lock Box.... I use these boxes along with the Python cable lock and have not had a camera stolen since. Box is lag bolted to tree and lock cable wrapped around tree and secured to box.
"I wonder if Cabelas will honor it since they are owned by Bass Pro now. Wouldn’t hurt to call and ask."
Cabelas will take your Bass Pro card and convert it to a Cabelas card. I did this last fall. Just go to the customer service desk.
