The military activities are not a regular thing, and the area is open about 99% of the time.
Just keep an eye out for military or Coast Guard
boats, and generally keep the
VHF on 16 - especially so if you see patrol craft. I've been
boating in the area for about 25 years, and maybe twice we were hailed on 16. One time we were told they were shooting 50 caliber rounds, and the other time might have been dropping dummy bombs, or something to that effect. The "Target Ships" - old WWII ships, across from the mouth of the
Potomac used to be bombed and strafed, and rocketed, regularly, and show the torn up
steel plate to prove it, but that was mainly before my time. One of them is sunk just below the surface, and a hazard to
navigation if you are not careful.

Back in the 90's you used to hear sonic booms quite a lot over near the Eastern shore from the nearby Patuxent river naval air base planes - but I believe that stopped quite a while ago due to some rules or
regulations. It's a great area, as
Chesapeake bay as it gets, and
anchorages are everywhere. As stated, be very careful for fields of crab pots, and especially near the mouths of rivers, where they are usually concentrated - but they can be anywhere about 30 feet or less in
depth. Usually if you see 1 there are another 100 or more nearby in several rough lines.
