Honestly it's NIMBYism. I feel for the staff at NOCA because they have a big job and a small budget, but it's so easy to fall into this type of thinking... "we used to have such a nice quiet neighborhood."
Take the recent bear issues at Cascade Pass. Here is what NOCA says on their website:
Blame, shame, and punishment, without sharing any responsibility. This isn't helpful communication. I didn't learn anything except that I'm probably a bad person who shouldn't visit the park since I'll ruin it for everyone including the bears. The signs they put on Cascade River Road have much the same message.
I also don't see how this helps the bear. Maybe some friendly educational signs, plans for food storage lockers, I don't know. I wish I could see that the park service was stepping up, but the message we all hear time and time again is that park visitors are a problem they wish would just go away. What if instead we accepted reality and got to work? I personally care much more about protecting the bears that actually live in the park today than some abstract and problematic idea of "untouched wilderness." I don't think angry signs and punishments are going to do the job.
