Stayed on US NAVY mooring ball (free if available, or anchor) in Weems Creek for 3 nights. It had all we wanted: the bay is nicely sheltered, pretty/scenic, good cell and OK-ish wi-fi connection, and a short dinghy access to shore with access to the strip mall, small restaurant and grocery store.
It was out first stay, and we liked the place.
Inflated dinghy, installed an outboard motor, did some repairs, tried riding it.
Couple of times went to shore to pick up some groceries, had a lunch at pizzeria, and just walked around.
