In the wild after a rainstorm the humidity in a burrow or any hiding spot is likely to remain at a very high humidity. I always provide a humid hide and my snakes during shed will stay in there for multiple days by choice. 70 somethig percent humidity temporarily is fine. I would bet that herp keepers in the south probably maintain that humidity level most year round.
Also, really grcforce? Forums are about discussion and opinions being shared, not just reciting "facts." There's no set manual on how to raise herps. It's not productive to be Captain Hindsight and tell people what "should have happened."
