Had a 4th of July tour with a great couple from Chicago, Rick and Katy. Both are avid backpackers, meeting 7 years ago on a 75 day backpacking, hiking, rafting and climbing trip, but had never tried mountain biking. Rick stays in great shape training for marathons which he runs to raise money for a kids cancer charity, and Katy stays in great shape working out and commuting all year to and from her job at the Cook County Courthouse. We had a exciting ride through Overend Mountain Park, even knocking out trails like Star Wars and Browns Ridge. With a room they rent in Chicago through AirBnB, I now have a place to stay and a couple of very cool new friends to see next time I make it to the Windy City.
