I was just reading a thread about the worst trail towns. I too couldn't come up with any, but I did come up with this. Just walk away from these people. No off color remarks needed, just walk away. They are the folks that you ask a question about the trail, and they come up with (now say this in your best Yoda voice) "why tell you should I, it would make your journey less fulfilling", "your experience would not be the same if I told you", or some such nonsense. Fortunately I only came across 2 of these folk, but it was enough to come up with my own little catch phrase name for them. A real Yoda quote..."Always pass on what you have learned"
