Several parks in Georgia are named after people, and most of those folks are either military leaders or legislators. Stephen Foster got a state park named after him by simply writing a popular song in 1851 that uses the river of the state park in its title and lyrics. From what I read he just picked a random river in the Southeast that had a nice “poetic” name and then wrote “Way Down on the Swanee Ribber” (listen to it).
The state park resides in the swamps of the Okefenokee National Wildlife Refuge and the Suwanee River cuts through it. We stopped by on our way back from Florida, had a picnic, toured the museum, and hiked the nature trail. If we visit again I’d like to rent one of the canoes or boats from their marina and follow some of the canoe trails.
