We did a little exploring this morning on the Badger State Trail. This bike trail used to be the Illinois Central Railroad corridor and includes the Stewart Tunnel - 1200 ft long and, because of the bend in the middle, pitch dark. We parked nearby and let Walter ride his bike to the tunnel. Then we got out our flashlights and walked through the darkness. It was pretty cool. Walter thought it was great to be "rained on" inside. Is there no end to the magic of trains? I think not.
(With a long exposure and a flashlight you might even see some ghosts!)
