If I were going to be in town I woould ride with you
relatively easy way:
Park in Sausalito near the 101/1 exit. Take 1 until you see signs pointing up to Tam When you get to Pan Toll, keep going to Ridgecrest. That is one wild ride down, spectacular view of Pacific on the west and Bay on the east.
Take Fairfax Bolinas Rd down to Alpine dam then on to the People Republic of Fairfax.
If you look on routeslip.com you should find far better directions than I can give at 6am.
If you can do it next saturday, the 23 of June, I'll lead.
if it remains hot, 1 may be at a dead standstill with cars wanting to go to Stinson an the other beaches. It would make the route pretty much impassable.
