I find that locks only keep the honest out and a neighborhood attitude is a better deterrent. I went into this discussion expecting peer pressure to utterly humiliate the dishonest and irresponsible. It has been quite an education. I, instead, conclude that the trail experience is in deep trouble. And to prove my point, wait for the proverbial "drama queen" or "oh brother" comment. There is a larger segment than I had thought that don't give a rat's arse about anything but their own self absorbed world and feel they should always be the final say as to what should be done anywhere. As I walk through these groomed paths, I stand in awe of God's creation and those that provide such trails. To me it is a reasonable attitude to seek on my own what those that provide the trails want me to do while on said trails. I am a guest on any spot I walk that is not my property. It is my job to know what to do there. It is not up to some authority to spank me if I am a naughty boy. Any other attitude is childish, boorish, and destructive... but alas, fast becoming the norm.
