Tried a great new place to ride in SE Michigan this weekend (for all of us who have not fled this festering sore of a state yet). They connected three Metroparks (Lower Huron, Willow, and Oakwood) with a paved trail, round trip is 30 miles (We did the whole thing). Although I saw a lot of bikes, the trail never felt crowded, and almost no kids on Wal-Mart bikes! At least 1/3 of the riders I saw were 'Clydes like me. It was a good mix of open trail, woods, small hills, very few road crossings, only $4 to get into the first park. I rode with the wife, so average speed was down around 12-13mph, but I felt comfortable cranking it up to 16-20mph every now and then. I would recommend you give it a try if in the area. I plan on going back by myself and trying an all-out hard ride for the full 30 miles.
