I can't find the post, but someone was looking for raw olives for home brining. It's too late for this year, but I found an olive grower at the Baywood Park Farmer's Mkt this week:
Cisneros Quality Produce and Gourmet Olives
Ed & Lois Cisneros
They pack olives themselves, but will ship raw olives at harvest time for home brining. They are mostly Mission variety, but I believe he has a few others, too.
This gives you time to do some homework and make shipping arrangements for next fall.
