Happy Sunday. I’m pleased to inform you that people have been pulling some really weird things out of rivers. In late April, the Fish and Wildlife Service caught—and swiftly released—a 240-pound, 6-foot-10-inch fish in the Detroit River. The female sturgeon is estimated to be more than a century old. “She likely hatched in the Detroit River around 1920 when Detroit became the 4th largest city in America,” the Alpena Fish and Wildlife Conservation Office wrote in a Facebook post about the catch. Around the same time in Florida (why is it always Florida?), two scuba-diving amateur paleontologists discovered a 50-pound mammoth bone in the Peace River.
