Skip the fence crossing idea, I've tried it and they avoid the crossing like the plague when there is a blind set up with in bow range. They have to have water and that's why they will come to water with a new blind set up near by, but believe me, they will find a way through the fence in order to avoid getting close to a blind just to get to the other side of the fence.
Be proficient for long shots, and hope for close shots. A range finder is a must!
