Combined a little work with a visit todayand inhaled 3 dozen of the extra small sweetwater.
Not quite as good nor as sweet as Kumamotos (they were out), but they were very good, and even the XS were MUCH bigger than Kumos.
Its been discussed before, but basically you sit on wooden picnic table on the bay and shuck & eat. Its kind of fun.
Drove by Tomales Oyster company a few miles South on the way out but didn't have time to stop. Next week.
