If you can wait until September there is the Warren Twnshp. backyarder at the Mt. Bethel Firehouse. Small comp, just chicken and ribs, an hour between turn-ins. First contest I ever did, have done it each of the last three years. Always a good time. No prize money, just ribbons for the category winners (first thru third) and a fireman's helmet for the GC. Small donation to the fire company for the entry fee, the last three years it has been $75, can't say if it will stay the same but I'd bet it will. Feel free to PM me for more info.
I just got info on a contest on Father's Day Saturday in eastern PA. I will post details later tonight.
