I think over-all it was a fair discussion and at least everybody wanted to keep the trail open. While some of Karen's statements were over-the-top and rediculous, it is very hard to argue with most of her points. I'm not sure the trail needs to be "restored" but we certainly need to ensure that more of the trail doesn't become like the little sluice.
It only takes a small percentage of the current users of the trail who deviate from acceptable usage of the trail to destroy any credibility the rest of us have. Little sluice being a sideshow isn't the problem, but the 30 drunken morons leaving garbage and SHIT (literally) everywhere are. People like Karen, hikers, old farts that have been driving the trail for 50 years, real-honest-to-god-tree-huggers that want to shut the trail down, etc don't care that those 30 people are maybe 1% of the people that actually use the trail. They only care about the damage they have done. Its up to everyone else to keep that 1% in line, or even off the trail, or we will eventually lose the access to the trail.
Luckily organizations like FOTR and RTF have made it a point to maintain the trail and increase policing of the above idiots.
