August, Sunday 29th would be a great day to do this. I was thinking about the Marin Headlands/ Sausalito Ride. We could start at say 10:00am in the city and have lunch in Sausalito.
I am a newer Vespa Rider who just wants to get out and ride. I have gone over the GG Bridge and really enjoyed the Headlands. Let me know if you are game.
Send me an e-mail. Looking forward to meeting other like minded Vespa riders.
