Day 21: 44 miles to and from the Illinois Railroad Museum where we walked 4.5 miles today. Dad got in free because it is father's day.  It is the largest railroad museum in the country with about 450 different rail cars and engines. We enjoyed riding on an early interurban similar to what would have gone from St Johns to Lansing 100 years ago. And we road in a 1916 passenger car pulled by a 1917 steam engine. We wandered through 5 huge building full of various kinds of trains, trolleys, passenger and freight cars, a train station and displays of all kinds of train items large and small. We had lunch in a diner and dinner at the Chinese buffet. A fun but tiring day. We head for home tomorrow.
PS One railcar is set up to sell used train books. Dad asked "I know this is a silly question, but do you have anything about train whistles"? The fellow handed him 18 different copies of an out of print magazine called Horn and Whistle. He was a happy camper!
