Grant's Farm has free admission. There is a $5 fee per vehicle to park, so load up the van and head over! The tour guides on the tram through the animal preserve to the main area are wonderful and full of interesting facts about both the part and the Bush family, founders of Budweiser beer. After you get to the main area there is a small zoo with a petting area where the kids can feed baby goats bottles of milk. The animals all appear to be healthy. The park is small, so it doesn't wear you out like the St. Louis Zoo. We try to get over here every time we are in St. Louis.
