My husband and I teach a 5th and 6th grade Sunday School class and are always on the lookout for reasonable yet fun things for the kids to do for afternoon/day outings. We live an hour from Evansville and not as familiar with the city and surrounding area as the residents would be. The school trips have included Angel Mounds, the Science Center/Museum, CMOE, Planetarium, and the zoo. We would love to find a really nice park for a picnic lunch. Other than that, are they places that could entertain the kids for around $5-10.00 each? Thank you for any information!
