Some people who have helped hikers for years are setting up a new shuttle service. They offer to pick you up at your car and take you to your starting point for gas money!
Give them a call and check them out. Spread the word! I called them and got a ride the next day from Giant City Lodge to Pine Hills Godwin Trailhead West end, though with a loose group of volunteer drivers, availability is subject to their schedules and one day notice is pushing your luck.. There are more rides available on the East end than the West.
5/16/17 A new service! I haven’t used them. They are in Carrier Mills.
