This Incredibly Talented Horse Is An Amazing Escape Artist

Stall, barn door or gate, no latch is going to keep Mariska the horse from going where she wants to go. She not only unlatches things for herself, but other horses as well.According to her owner, Mariska the horse, who they've nicknamed "Houdini", learned the latches one step at a time. Safety latches have now been installed to make sure she doesn't roam. But if those latches aren't in place, well you see what happens.

What I'm wondering, how long before the horse figures out how to unlock the safety latches and roams free again?
