Our daughter had done this ride a couple years in the past and had done so with her small kids, but even then the thought of riding 15 miles on bikes with little people was kind of frightening. We had a great time, plenty of time to go through the tunnels and stop along the way at all the informational signs. (Perhaps since we went after Labor Day, there were less bikers?) As I made reservations for bikes and trail passes the process didn't make sense to me, but after the ride I understood the process.
Makes me want to read about the fire of 1910.
