My family and I will be visiting Tybee Island in mid-October. I have read on some of the charter tour websites about "fossil hunting" When I called to book, they said it is on the banks of the Savannah River near the shipping piers and needs to be done at low tide. Well, we are unable to do the charter at a good time for fossil hunting, and am wondering if it is something we can go do ourselves. Anyone familiar with this??
