I did the 60-whatver route the first time and the easy Green River route out to lunch the second time, coming back on the metric century route. It's a fun event, and they feed you well. Both times I camped at the start/finish. Very friendly atmosphere. I went to high school at Deerfield Academy (class of '83), so going back is like a homecoming for me. If you do it, make sure you take a spin around the town and campus. There is a historic inn and church and some historic houses on the old main street that runs north.
