I like to get blue crabs in the marshes off of Barn Island on Stonington, CT. I usually anchor out in my sailboat for the weekend and go out around 4AM with my dingy and a flashlight and net them in the shallow water. I steam them up for breakfast and drink a beer and watch the sun rise.
Also at low ride I can dive down and grab a quohaug and stuff my pockets with them, get enough to steam up as an afternoon snack.
