West of Tallahassee on Highway 20, a little hole-in-the-wall called "Crow's Corner" makes some superb burgers. Their frogs legs and pork ribs are great too!
At a Vintage Car show in Quincy, Florida, we ate from a nifty rig - the "Beetle Burger"! An actual VW Beetle converted to a towed BBQ/Grill outfit. Engine cover was the fire pit, whole interior had racks for the meat. They put out a pretty fair burger with all the trimmings!
Maybe not the BEST burger, but the cooker was sure 'hot'!
