I dunno, I think it still comes back to the rider in the end. Make the rider safer and you get the biggest bang for the buck.
Unless the track has surprise spring boards, pop-up walls, trees that grap the throttle, brake, clutch, or kill button, how could you actually "blame" a track? Could it be made "safer"? Do we want it to be made "safer"? You bet!, but at the expense of what? Fun? Then why do it? I know that sounds ridiculous as it did to me while I typed it, but why would we take the risks we do if it wasn't some sort of fun? I do not take near the risks I used to due to my "fun" ending in pain. Tracks didn't change. I did.
Not saying we do not try to make things safer (the bike, the tracks, the equipment, etc.) as that is a given or at least should be. Any track owner that just shrugs he shoulders when a rider gets hurt on his track should be ashamed, however if you make a "100 % safe track" that is no fun or is not challenging to ride on while another track is fun and/or challenging for most (never going to satisfy everyone), well, who's going to ride it? Not many. The safe track shuts down eventually due to not enough riders...
Sure, we all push, and/or have pushed the limit a time or two, some too many in some peeps eyes, but 'tis the dealio. I read it reference to, but I got hurt so many more times on my 450. I feel this was due in part to the fact I could ride it faster without so much effort as my 250 smoker, hence when I hit the ground, it tended to mess more stuff up. I don't blame the bike though. I blame yours truely.
A track is what it is. If I saw tracks making SX triple style gaps/jumps, rythm sections (Steel City had a section that hurt the average rider), etc. that would be excessive for the average rider I think and THEY should decide not to ride it or roll those sections. I've failed to do that on occasion, hit the jump a couple times in fear and it caught up with me eventually if I did not stop it and quit trying to compensate for my lack of corner speed with other methods to huck that damn jump (Dayton SX ametuer day broken femur). Heck, even for some of the best, Blake Bagget for example the last couple of years... It happens. It's dangerous. Treat it that way
It sucks when someone gets hurt. Quit trying to blame someone else other than yourself though... I think most who get injured know where the blame lies.
And you tracks, quit making the tracks so damn fun that we get hurt doing it. Just make a NASCAR oval. No one has ever gotten hurt in NASCAR, right??...
Where's my bubble wrap? I'm done. See you at some unsafe track near you...maybe. Grassy backyard with trees, stumps, flint, roots, rocks, etc. may be safer for me to ride on...
