I wasn't expecting much either, but...
I got a call today from the service mgr. of my LBS.

He talked to the Trek people, who offered a new frame. He told them that the components wouldn't swap over, as this bike was around 20 years old. They agreed to replace it with a BRAND-NEW TREK 820!!! How sweet is that? Apparently, the people at Trek didn't press for proof of purchase, and he didn't remind them. The bike should be in town next week. And I still have my 30-year-old Fuji S10-S, so I can hang out here with you fine C&V folks, and keep the Fuji on part-time status. Happy, happy, happy.
