Just like dad

We went to the Pittsburgh Zoo two days in a row last week. What a great way to spend a couple of not-terribly-hot days.

One thing that we found too adorable were the beavers. The father beaver was hard at work building a dam (first video). The baby beavers were imitating him, sometimes helping him, and sometimes trying to build their own dam. We called it "Beaver Fort." But how cute are these flat-tailed rodents?
