A pop culture convention will be held this weekend in Wooster.  The event will take place Sunday, from 10am-6pm, at the Wayne County Fairgrounds. In addition to a cosplay competition and 20,000 square-feet of vendors selling collectibles, Sunday’s convention will also include appearances by three actors from the film “The Sandlot” and a “Star Wars” voice actor.  The convention’s organizer says the hope is to be able to turn the event into an annual occurrence.
