We came to the spot where Riotti and some friends had built a fort in the winter. Needless to say, it was no longer standing, so the kids and Riotti decided to try to rebuild it a bit. I think that they would have better luck if there were snow to use as mortar or something like that. We then went from the main part of the nature preserve to Stair Park, which is sort of a back entrance to the preserve that we have not been through. There was a pretty waterfall and then we walked along a trail we had never done before. Then Caleb decided he was tired and so we had to retreat, but I think we'll head back there again soon.
