Southern hound just returning from a long New England vacation; 3700 miles driven, beginning in ATL.
While in PA, I enjoyed the best authentic Neapolitan pizza I've ever had: Dominick's Pizzeria in Pine Grove, PA (off I-81 north of Harrisburg). The 16" meatball pizza was perfect. The crust was about 5/8" thick and a bit chewy. Excellent pizza sauce, too.
If there's better, I'd like to know where.
