Supertwins last year = 6 to 7 guys on the track at once with 6-8 second gaps in lap times. Sounds like a lot of clear track practice to me.
I'll have a chance to observe & watch the Unlimited classes for awhile and get some practice in the less populated grids, before I decide if I'm going to jump in deeper.
I know there's risk. There's a risk doing track days. There's arguably a hell of a lot more risk riding on the street. There's risk just driving to work every day in my truck, maybe even more so, because of complacency and idiots with bad driving habits.
A few years ago on I74 a guy was driving along minding his own business. A pickup truck was travelling the other way on the interstate, and the guy was carrying a load of material with a tarp over it, weighted down with cement bricks. The wind caught the tarp, flipped a brick up and over the dividing ditch nearly 100 feet, through a guy's windshield, and through the dude's head.
Another local woman was killed more recently by a random 400 lb block of concrete falling off of an interstate overpass that was being repaired. It just happened to vibrate loose from work being performed on the other side, and went through her windshield.
Shit happens, and you never know when your ticket is going to get punched. I don't see risk - at least not controllable risk - as a deterrent to enjoying life. We're not playing russian roulette. We take a lot of time to prep our gear, our bikes, and ourselves, and to practice good habits so we react properly when we need to. I know enough not to get myself in over my head, and I know enough to watch the guy in front of me to recognize if HE is getting over his head. I carry a consistent line, to minimize the chance of getting packed from behind.
Even if I lived the safest possible life and never left the house, someday I'm going to die. Could be from a lightning strike, a flu virus, or a heart attack. Who knows?
All I know is that if I went through life afraid that everything out there might hurt me, I wouldn't really be living at all.
Anyway that's enough philosophy and depressing thoughts for one weekend. I appreciate your concern, really, I do, and I share it. I know going in to this season that there's a possibility that someone I know may end up getting hurt.. may be me, may be you. It sucks that there's a cross to bear as a byproduct of this hobby, but we all do this for our own reasons, and we all know what risks we take when we put on gear and hit a hot track.
