We went to the neatest Pumpkin Patch this last weekend! It was hot though. Too hot. Too hot to pick pumpkins in October. We had tons of fun though! If you live anywhere near Franklin, TN I would suggest a trip to Gentry's Farm. They are very homeschool friendly too and it looks like they have a great summer day camp program.
There is a pumpkin patch where you can pick your own, a corn maze (shaped like a cow!), a hay maze with cool little slides and tunnels throughout, a few animals, lots of history, corn/grain troughs for the kiddos (and big kids), a big barn with lots of centers like a farmers' market and linclon logs, a hay ride, nature trail .... tons to do and really a great price.
Pumpkin carving and painting begins tonight!
