Sierra Madre has a new farmer's market which debut this past May 2008.
The market is open from 4pm-8pm on Wednesdays, which initially was 3pm-7pm, but many people missed out because of traffic and time getting to the market after work.
I was planning to go check it out and take some video and pictures. I'll post when it is ready.
There is talk that San Marino is trying to have a Farmer's Market on Sundays from 9am to 1pm.
