Playing with ice

We were half an hour early at the <a href="http://www.chias.org/">Notebaert Science Museum</a>, (a/k/a "The Butterfly Museum," but the guard decided it was too cold for us to wait outside so she had us come in an sit at the tables by the gift shop. We discovered the stroller had picked up a lot of snow on the way over from Betsy's, so we made snowballs. Here they are showing them off--except Wrenna doesn't quite have the idea. Note the mittens.
