TN: Tennessee. No mention of swamps on its wikipedia page. There are three bloody great major rivers mentioned and mountains, so I'm thinking hydro powered cattle prods, weights and a river.
You should be able to sell a carbon credit or two on that basis.
some of west tn is "false karst" highlands; we got ~10ac to ~1000ac patches of swamp all over. some of them have the fun floaty landscape bits that you can walk on, but not drive a tractor over. eats bulldozers with an amusing plonk sound.
