I just read about this over on Laughing Squid. From Scott Beale’s article (and photos below) the Lost Horizon Night Market is a “word-of-mouth participatory event featuring a series of box trucks parked along the street stretching for several of blocks, where each truck has a unique theme that is revealed once you part the curtains and enter the truck. The only way to find out the location of an event to be invited by one of the truck’s proprietors”. Click on the full article with many more pictures. This is practically in my backyard; bummed that I missed it.
