We have a name for a reinforced basement here in Florida; it's called a swimming pool. If I dig 18 inches down where I live, I get water. LOL Of course, in a few hours I won't even have to dig to get water; I'll have a lake in the back yard. My horses are in the barn, with half a roof due to the last hurricane. When we put them up, they gave us this, "Not again!" look.
Yeah, horses are a lot like monitors in some ways. Including remembering which way they got out the last time. But my one horse can open spring clips to let the other horses out; something my lizards have yet to do.
