Thanks for your replies to my PM. From the replies I have received, the votes are as follows;
Point Reyes 4
Fort Point & GG Park 3 ( I put them together as they are so close to each other)
Marin Headlands 3
Alcatraz 2
Point Reyes is favourite so far. On the way there is also Point Reyes Station, seems like there will be some photo ops there and good food. There was an article in the SF Chronicle 96 Hours Supplement yesterday;
Highway 1, Point Reyes Station
Just so everyone knows, I'm happy to car pool, I have a Jeep so there will be room for camera bags and tripods.
There are four Saturdays in March; 7, 14, 21 and 28. Post the weekends not suitable to you (that's probably easier) and we'll work it out from there.
