Another interesting museum in Forest Park is the Missouri History Museum. It, too, is free except for special exhibits and is a great place to also get help with genealogical research.
During
early and late summer, they even have concerts on the front lawn
---called Twilight Tuesdays. Local bands, but very good ones, like Dogs
of Society-a Tribute to Elton John--are the free entertainment. We saw
them in 2014 and they were "brilliant".
