My fiance and I limited out in about 2 hrs on April 8th last year so its possible. Gonna have to fish real shallow water though, less than 4 feet. Should be a bunch of shad down there and some stripers.
I know this is not flounder, But if you are looking to do some catching...I would try going out on the Morningstar with capt monty. The tog should still be good. I went on sunday and there was some great fishing after we made the second drop. In fact one guy on the boat caught the new state record. For $100, its hard not to go with the Morningstar, if you want good odds on pullage and something to bring home for the table.
I agree that the flounder action might be a bit slow/ Early season behind oc is always dependant on good weather, meaning clean water. If its dirty and cold, you'll have a hard time finding a consistent action.
