While I was able to get the Cobb pool, they could not find lifeguards. The county requires they be county employees and none were available. March is a 5 week month. That means there are 5 Sat. and Sunday's. I don't charge for the 5th week for reasons like this. I know there may be times I can not find an alternate pool. You still will get a full month in. You may also come an extra time as well if you like.
