Take a stroll downtown and check out all the boats docked is Ego Alley; while you're down there why not check out some of the local shops!
Grab a signature sandwich or some hot sauce from the hot sauce wall... you can also grab some wicked good pickles.
Jon and I love to grab a quick bite and chill out downtown.
Miss Shirley makes a mean breakfast, check it out if you've got some time.
Jon and I walk on to the Navy campus whenever we have some time downtown. Security is relatively easy to get through and you can walk along the water and really get to see the campus.
Take a tour of the State House.
