Been lucky enough to see hail four or five times. The first time was in Delaware in the parking lot of a Sonic. Twice we had hail at my parents house in Pompton Plains and we've had it twice in Mahwah since I moved here almost four years ago. Largest hail I've ever had someone I know witness in this area which was golf ball sized which occurred in Butler, NJ almost ten years ago.
And then we had this freak storm from 2011 which brought baseball sized hail to parts of Queens and LI.
