We played on the playground
the big inflatable slide (which was actually pretty fun for me)
we ran around the straw bale kids maze
picked out a pumpkin
we even got to pick some flowers.
They had a corn maze out there as well, but by the time we got around to it both of them were pretty cranky. We would have had to pay to go in the maze, and I didn't feel like spending money to carry around two crying babies.
