This is a shot taken in one of the tunnels on the Elroy/Sparta trails. There are three sets of tunnels, two of which are 1/4 mile long and the third is 3/4 mile long. They used to be part of a railroad system, but are now recreational trails. The tunnels are so long and foggy that from the middle of each tunnel you cannot see either end. There is also an extreme temperature change as you go into each tunnel. If you have not been on these trails, take a day, and bike or walk them.





This shot shows you a tunnel entrance. The hazy look is the dense fog.
