Go to California and visit the beaches there in Huntington Beach and Newport Beach and you ll have a grand time. Or go to Hollywood for a look-see.
Which coast? You need a starting point before you can have a destination. You can t go wrong with the national parks. Here s a link:http://www.nps.gov/index.htm
New Orelans has amazing food.
Key West is one of my favourite places. Mexico is a blast, South Beach Miami is really nice.
