There is clearly a time and place for thin crust pizza, but having grown up in the neighborhood of Old Forge, PA pizza, I learned to love pizza with body. Old Forge is famous for it's double crust white pizza. I used to eat it by the tray. If you haven't had it... it's definitely worth the pilgrimage. Ghigarelli's, Arcaro and Genell's, and Revello's were my faves back in the day.
Luckily, I now live 30 minutes from New Haven which has some pretty famous 'za in it's own right, albeit thin crust. Pepe's, Modern, Bar and Sally's are all top notch.
