Went for a hike a few days ago at Drake's Estero, in Point Reyes National Seashore. I've been meaning to get out there forever, and it didn't disappoint. You can't see it in this picture, but the estero is full of all kinds of birds. Everything from cranes to a zillion ducks to sandpipers and seagulls. Once you out above the open water of the bay a bit more, you can see the oyster farmers hard at work. In fact, the night after this hike, we had fresh oysters with our dinner that could well have been harvested by the very men we watched splashing along in their hip-high waders.
Plus, how can you go wrong hiking on a day in January that looks like that??? And, of course, with company that looks like this :-)
