For pizza connoisseur Todd Mead, it's both educational and sentimental. "It feels like a big pot of nostalgia," Mead said Saturday night at the event he organized as a way to get him back in touch with his South Shore pizza roots, but also gain feedback for his future pizza-making excursions. Mead organized a blind judging featuring 10 pizza places on the South Shore as a way to gauge how his pizza, MASSively wHOLEhearted Pizza, compares with more established pizza places, as he attempts to launch his South Shore-style pizza truck in Colorado. "I'm not bound by a recipe. I have a chance to create something special," Mead said.
