I'm a Baltimoron : ) Maryland has more of the bay than VA, plus MD owns most of the Potomac River. Virginia has better politicians, lower taxes, and better gun laws. You could sail the Chesapeake for years and not run out of gunkholes to anchor.
Water temperature in the Gulf of Mehico or the Florida Keys is the best. When the water gets warm in Ocean City, the jelly fish start stinging : )
I miss the place but not the politics. We visit at least once a year. Still plenty to do.
