Truthfully I'm not an expert on snakes but it sounds like you will be O.K. as long as you keep it dry. I've mounted two eastern diamondbacks for a customer and have a 6 foot diamond back skin I tanned on the wall. I simply went with a commercial tan solution but it's been so long ago I don't remember the details. Beautiful skins aren't they?

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
