Dear Lennard,
I definitely still have the Zinn.   I would never part with it.  Many cyclists have 15 bikes.  I only have the Zinn and my BMC.  I am so lucky at 72.  I race when I can.  Doing Race the Lake again this year.  Thinking of the Mt. Evans race, (have raced it twice) but I hate to hold up the staff at the top, since I know I will come in last.
ANYway, I will keep you in mind I’m the future, and pass your name on when I can.
I hope your family are fine.
Harvey
