Summer Heat!

Just how do you keep kids cool on hot days? We have tried everything around here, and it seems that heading to the creek everday is out because of the cost of gas. Heading to the pool was out on Friday because it was at full capacity inside and out. We have been doing the kiddie pool/sprinkler thing at least once a week with familyWe have airconditioning thank God! But how many more days can I listen to "I'm bored,"? If anyone has a different plan and it's working please let me know!
