Congrats on your century! It seems like last saturday was a good day for people to be doing centuries.

However, as you probably have discovered by now, you are probably suffering from post-epic-ride depression and wishing for another ride of equal distinction. I hereby open-endedly extend to you an invitation to come out to the Seattle area and ride with us PacNW BF folks. I'm sure I can't speak for everyone here but I'm certain a few BikeForums members from the area would love for you to join us on our rides... and that goes for anyone else in the area too. Maybe you could celebrate the anniversary of your first century with a set of back-to-back centuries next year and join us for the STP.
BTW, don't be too concerned about making the century "honest"... I think bike computers are liable to be a bit off over the course of a long ride...
