Fantastic, guys, many thanks for the tips. I've driven the "1" in a rental car before - the wife wanted to see the hotel where they filmed the "American Pie - Wedding" movie.
I'm an airline pilot, so my job keeps me away from my bike about 17 days a month. So I thought I'd treat myself on my next SFO trip. Will have to give this some serious thought.
PS: Can I 'filter' in the state of CA or will I get arrested for using a motorbike to beat the traffic? How do the highway patrol treat motorcylists? Have never rented a bike in the USA.
Slowpoke - awesome link, thanks!
