I finally got some info on this. I'm not too tech-saavy, so I don't know how to link to the article, but Today's Local News has a segment about it.
It will be this Sunday (April 29th) from 10 a.m. to 5 p.m. at the Thai Buddhist temple and center. Is that the one on 11th Avenue? I've never even noticed it, but I know there is one there. When I searched for Escondido and Buddhist temples, I got 5 different locations, mostly up by Deer Springs. Who knew?
