Grew up and went to College in Flagstaff. Never got to ride in hail there though (although I had countless missed opportunities).

I DID however have the experience of riding in that kind of Hail riding alongside Tempe town lake in Tempe Az at the end of a Monsoon season and was attacked by marble size hail. About every 8 or 9th stone would find a vent in my helmet and give me a sharp knock on the noggin. Wouldn't you know it that the storm caught me after I had gone under the last overpass and the hail had passed by the time I found shelter. That storm was a doozy. Every car that passed me would send a wave of water over me as the standing water in the road was 6 inches deep until the storm was over. I showed up at my meeting completely soaked to the bone.
