My parents have a super nice in ground pool. They put it in when Alex was a baby, so all of the boys have been able to enjoy it. It is heated also, so it does not have to be warm outside at all to go swimming! Alex and Nick love to swim!! They are learning to dive and do flips now so they are always wanting to go and swim! Mason is not the swimmer yet that his brothers are. He likes to walk around and throw whatever he can into the pool! So you better keep your shoes on the other side of the fence!! We are lucky to have a pool top swim in any time we want!!
