How does Lee ride without tires?

Posted by me on last year's thread:

Got up at 4:15 to get the gang moving. Delivered robo and V to the Davis Double about 5:20 where they met up with MP and Mr. MP

I also discovered that usn's doing the smarter route started in Winters at 7 am. We saw HotRod going up to the Dam (and the official AV greeting was born), we didn't see MP. I don't remember if we saw V. Both of them could have been stopped at the Dam rest stop.
