Thanks for the reply, jamawani.

I only need to ride to South Lake Tahoe one way. I'll be meeting with some friends there, and they will drive me back to the East Bay (I should have said this in my first post).

It seems like the Western Express is much longer than the route I suggested that's why I am interested in this one. This would start from Pittsburg (so I won't be riding through Vallejo or Fairfield), and go over the Antioch bridge (which I believe is bicycle friendly) to Hwy 12 and take it to Hwy 88 which goes almost all the way to South Lake Tahoe. From previous posts I got the impression that Hwy 88 is a good choice for the last part, so I was wondering if it's nice from the beginning. Also, how is the Hwy 12 section between Hwy160 and Hwy88 (i.e. between Rio Vista and Lodi)?

I know I won't have a problem finding a place to stay for the first part of the course, but will there be options say on the last 80 miles of Hwy88?

Thanks
