Someone must have fallen off the chair sometime after those pics were taken. The current bars on chair #23 have so many anti-slip under bars that it looks like the proverbial fine tooth comb. One have to be cognizant of all body parts prior to lowering the bar lest one of the errand parts get squished.
Didn't a ski coach have a medical event a few years back and fall off that chair? That rang a bell but I am not finding anything in a search. It seems like he was fairly high profile, or maybe just well known to some of the kid racers I know.
Also, Sunlight still has no bars, at least last time I was there. A couple center pole Riblets, yessir!
