I have spent many nights in that same camp site and never had a problem, sorry to hear about your experience. We have had bears in our campsite on top of little green mountain but the last time that happened was probably 5 years ago.
We saw the warnings at Ivestor Gap this spring but didn't have any trouble their either.
"The mountains are calling and I must go."
“I only went out for a walk and finally concluded to stay out till sundown, for going out, I found, was really going in.”
