Definitely make a trip out to Rum Point and have a Mudslide. Legend has it that the Mudslide was invented at the Wreck Bar at Rum Point.

Something else that might be kind of fun and different especially for the kids is rent a dog. Yes, you can rent a dog for a day. Here is the information and story if you are interested.
