If all goes well at the Board of Selectmen meeting tonight, Brookline might sign on to allow food trucks at nine locations around town. The area currently has only a few ice cream trucks and mobile vendors that visit construction sites, but nothing that belongs to the new wave ala Clover, Staff Meal or Go Fish. Alan Balsam, the town's director of public health and human services, says the hardest part of bringing food trucks to Brookline has been figuring out locations that won't steal focus from local brick and mortars. "We don't want to kill the goose that laid the golden egg," he says. Balsam could not yet comment on which trucks might come to Brookline but says that several local restaurants have voiced interest in going mobile, as well as "a waffle guy." The Brookline Mobile Food Vendor Pilot Program would last for six months as a trial, and its hearing tonight is open to the public.
