Good to see. It's not toos urprising; I've seen captive burms and retics climb when given the chance pretty regularly.
The local zoo has 2 female burms on display that will climb their rock wall on a fairly regular basis (the albino's particularly good at it).

Hell, even ball pythons can climb; I had an escapee when I was a kid get into the ceiling :D
