I thought is was 150 yards. 50 feet from the center line would be even better, because the fence used to be 10 feet from the road, then the state came and took another 10 feet (10 feet for a mile works out to 6 acres apparently) so the fence is now 20' from the side of the road. This would make it easier to try and shoot corner to corner for a distance of just over 1,900 yards.
