Meteor Showers...
Two years ago doing the overnight Governor's Cup from Annapolis to St. Mary's, we were treated to sporatic "shooting stars" from below West River to Pt. Lookout (except for a few miles on either side of the Cove Point gas dock).
On the upper Bay, to add to Rich H's spots, possibly the outer Bodkin Creek, and anywhere on the outer Sassafras or off Aberdean would probably also work.
