Some days, I don't have much of a story to tell. These are the lovely shores of the Marin headlands, where there are myriads of quiet bays, lovely beaches, hills and valleys. I recommend the visit if you've got the time. Despite being in full view of half the bay, it can take some good navigating skills to get out to the various parks and reserves and wetlands. Bring binoculars, and jerky. I particularly recommend jerky. Going to go smoke some today actually.
Jerky is probably illegal on Eynhallow. You'd probably have to bribe some official or other in order to get a license. I don't suspect this would be difficult.
