Since I started chasing in 1985, only had to replace one windshield..... from a 1999 chase near Carrier, OK. Back then, data was picking up the 'bag phone' and calling in to the station for radar interpretation. I was working with a OKC station at the time, and wound up getting into a heavier-than-anticipated hail core. Lost the windshield on my Suburban. And to add misery; the next day while on my way in to get it fixed, an OHP officer pulls me over and gives me a ticket for having such a damaged windshield !!! (Arghh!)
Other than that, I've been fortunate and started playing it smarter to avoid heavier precip if at all possible.
