I have a chance to hunt next week on a farm that has some really nice deer. 1500 acres and only one buck taken so far. The rut is over and cold weather is headed in. There are a lot of big bucks around. I saw one last time I was there that would go 170 or better, but about 100 yds away. The place gets a lot of pressure but mostly gun hunters. I'll be bowhunting. What is the best way to get a shot at a big buck?
