I visited this neat holiday layout yesterday that features G, O, HO and N gauge trains and is run by the Kishwaukee and Eakin Creek Model RR Club in the Prairie Lodge of the Del Webb Sun City in Huntley Illinois every day from 11 am to 3 pm weekdays and 11 am to 5 pm on weekends. It's free and open to the public. There's a signup for a raffle for a Lionel train set (ea. tix $2).
Today I visited another layout in McHenry Savings Bank in McHenry, Illinois that is open from 9 am - 5 pm (M-Th) or to 6 pm (Fri) or to 1 pm (Sat) from Dec. 14-3. It's free too and includes some beautiful models of American Flyer, Ivers, Hafner, Hoge and Lionel from the early 1900s through today. This layout is nifty because you can control a loop of trains from each corner. There's a signup for a free raffle for a Lionel train set.
