Just out of curiosity, I went back through North Cascades Route Reports, scanning for TRs, looking for negativity and abuse. I went back eleven pages to August, 2003. Well, I found little evidence of it. There was just Klenke's crack about sewing it up on dryad's thread about the Beckey Route on Liberty Bell and that was pretty mild.
I would say that recently, there just hasn't been a lot of problems. Maybe I should go back farther or look in Alpine Lakes (Tooth), but it's beginning to look to me like the problem has been overstated.
