WILKES-BARRE — Food trucks can be hard to catch in the wild; hunting the elusive eateries is part-luck and part-Internet savvy, but on Friday, June 24, a herd of mobile meal trucks is scheduled to graze just off the Susquehanna at Nesbitt Park. Arranged as a kickoff for Riverfest 2016, the city’s second Riverfront Food Truck Rally will run from 5 to 10 p.m.
