the wildflowers are quite spectacular right now (in Palo Alto, they're pretty much over already).
These mustards are at McClures Beach, nearly out at the north end of Point Reyes. One reason why they stay vibrant late into the spring is the fog. Here's how Bolinas looked this morning (well, the view is from Bolinas, looking at Stinson Beach with Mt. Tam behind).
But Mt. Tam was above the fog. Here's what the weather was like up there.
And the Mt. tam wildflowers were further along. Still beautiful, though.
