Pedernales Falls State Park
We got a state park pass and hit up a few parks, starting with Pedernales Falls. This park had a duck pond marked on the map, so we tromped a mile along a muddy trail (in the only shoes we brought) to get to it. Eventually we found the muddy pond that was supposed to have the ducks. But there were no ducks. So instead we fed our bread to some ants. They were pretty happy about it.
