When I was a teenager I lived in Mi and back then there was no helmet law so of course I never had one. Anyway one night I was rideing to my girlfriends house out in the county when a junebug hit me ( or did I hit it lol) on my forehead. Holy crap , liked ta knock me off the bike ( prob doing 60/70 mph) and when I got to her place there was a lump that looked like someone hit me with a bat lol hurt like hell for Cple days !! Will never forget that !! Yrs later while rideing in woods ( wearing all raceing gear ) my friend that was in front of me squirted a rock the size of a golf ball off his rear tire that came at me like a golfer had just hit it with all his might lol and thank goodness was wearing helmet that day cuz that would have hurt lol but brought back memories of that bug for sure
