Daniel Taylor had this wonderful story linked on his blog. I wanted to link it, too, since it's such a wonderful story!
(This made me nostalgic as well—'cause I've been to that farmer's market. On the 1978 California trip with my parents, we got tickets to see Match Game, which was filmed at CBS Television City, and we ate lunch at the market. I know it was 1978, because they still had a poster up from CBS: On the Air, their 50th anniversary special which had aired earlier that year.)
