I also vote for the Flower Mound Pumpkin Patch. We took my niece (4) and my daughter (10 months) and they both had a ball. It was pretty nuts getting in and out, but hanging out in the actual patch, having a picnic under the trees at the tables, and riding the rides was awesome and totally worth the travel time and gas. Best of all, everything is free and you can bring your own food. You can't beat that anywhere in the metroplex. Everywhere else you have to pay to get in or at least buy something. Totally loved this place and will do it again next year.
