i think that some special hangars may have been ordered to repair these routes. standard 3/8" -1/2" hangars didn't fit the existing bolts. some folks are definitely making the effort to get these routes fixed.
whoever did this
i'm not the biggest fan of bolts out there but dog knows i've clipped plenty of them. these were nice, short, easy beginner routes. great place to take firs timers and great, super positive place for first leads.
