YES, it's a display called Secret Societies. There are 3 galleries at the History Center - Yesteryear is from the arrival of the settlers through approximately 1900; the Lyman gallery is the early to mid 1900s; the the Rambler gallery deals with lost Kenosha industries and a display dedicated to the 50th anniversary of the AMC AMX car.
No, just cool vintage cars, toys and equipment from the 1800+ all on display. Cool stuff and they sometimes do little shows. There is a freemason "Masonic" center but I don't think it's a museum, I think it's just a meeting place for them.
