As a swimmer of rivers I'm not sure you should literally tell people to go jumping in rivers (though swimming around on the edge is fine). Literally jumping in to a river might be exciting to do but its also a quick way to die if you aren't prepared for that sort of thing.
Correct. It just so happens near my house there is a microscopic beach along the hudson river where people can swim. On a day i really needed it, I jumped in the river. I hadn't swum in years. And it was nice.
