Leading up to Octobers spookiest event, Western New York’s fleet of food trucks will once more gather in Larkin Square for the 2015 finale of Food Truck Tuesday - this time, with Halloween approaching, competing in a pumpkin-carving contest and offering candy to costumed attendees.   As some two dozen food trucks from Buffalo and Rochester offer their signature fare with extra treats for those in the spirit, attendees will be able to vote for their favorite carved pumpkin from a row along the heated boardwalk. Also on the boardwalk onstage, Workingman’s Dead will once again don their Grateful Dead costume to close the season’s live music lineup. As usual, the event is free and open to all ages, with two bars serving beer, wine & soft drinks, and plentiful free parking.
