However don't despair! Don't loose heart, cheer up, what will probably happen is this:
Keep checking back on TE, maybe Craigslist (not sure what section), check with the Velo Girls and Lunachix bulletin board on Yahoo...you may find Princesses who registered but can't go.
There is a way for you to transfer the registration.
Mary and DP if you're here the weekend before the ride and can do the training ride with either the Velogirls or Lunachix. This last one usually follows the same route.
Last year the weather was blissfully perfect for the training ride and *&^%ing &*^% awful on the ride itself.
And...registered or not we might have a TE dinner the night before again? Hope to see you there then.
