Billy, Hal, Shelly, Wayne Smullen, Dave Dunklin and Hunter Myers those just the deaths. How many drivers and trainers you know, that are limping around from racing related incidents. How many concussions? Look at football helmets they've improved, when was the last improvement in our helmets.Do they still mandate vests at all tracks? I started in the 60's, not many updates. I've had my share of wrecks, broken equipment etc. I wake up every day sore and do limp, but I thank god that I made it through. It' s a dangerous business, don't forget it.
