Chris............ I have fished the Vedder/ Chill. system for 30 plus years and rarely see any problem during the winter season so its a few gerks that cause 90% of the problem. It has to come from law enforcement. However the general lack of respect for everything is at the root of all of this ,,I E.,,breakins, theft, vandilizing, school tagging and all of it. I know it may sound polyanna but at least the rivers , lakes , schools, private property we haven't seen the abuse you are experiencing up north. Its a sociatal problem. Mostly related to large city mentaiity. Again the big stick is the only thing they seem to understand.
Strong peer pressure and "we just don't do that" ,,,,parent to offspring influence is how it works here.
My mother was Canadian so I am Dual citizen and sorry to say I see a marked diff. in Canada............
Dam it we all need Respect , respect for all
