The marina in Savanna is within short walking distance of food and bait. Go north on main drag to Mannys for pizza and tacos. Cant go wrong there. Keep going north to Bp station for bait. I keep my houseboat in Island City harbor in Sabula which is a very nice harbor. But there is only one cafe in town and about 1.5 miles for bait.
Remember keep your lines in the water were all in this together.
