On May 22, The Bulletin ran an article concerning trail use in the Deschutes National Forest. In it a representative of the Deschutes County 4-Wheelers argued for the construction of "more trails that are designed with boulders and logs and things...to go over." She surmised that "(i)f you give them (drivers of Jeeps and 4-wheelers) something exciting enough to keep their interest, they won't go where they're not supposed to go."
This is precisely the method I use to keep my two kitties out of mischief. I am told that it also works well with very small children.
