Well, I survived :-)
Detailed ride report to follow, once I sort out pictures, notes, and my widely scattered thoughts.
Vitals: 18/19 finishers. I came in at 9:35 PM on Sunday with Bill, Chuck, Crista, and Joe, for a time of 65:35. Total mileage 622.9, rolling average overall right at 14.0 mph. Climbing claimed to be in the 40,000'+ range, calories burnt were over 35,000.
Couple of photo sets have been posted: one from Bill Beck, and one from George Winkert (who just happened to come by and take a few snapshots near the Gawdforsaken climb to Carbondale.).
