I am planning a two to three week trip with two 13 yr. old girls (I'm probably nuts!). I'm going without my husband, so I will be the only one driving.We live in San Jose and have toured California enough and want to go elsewhere. We can start in San Jose or fly somewhere else in the country and drive from there. We are considering Maine, Cape Cod, etc., but are open to other ideas. I need a trip that will keep teens interested. Help!
