Len, John, Joel, and Ben will be driving non-stop from the Chicago suburbs to Yellowstone National Park, 22 hours of sheer highway excitement. Two nights at Slough Creek to start the trip, followed by a 6 day, 5 night trek through the Thorofare. This trip starts with a boat ride from Bridge Bay to Columbine Creek and ends on the South Entrance Road near Lewis Lake.
