RE: What's the toughest animal to hunt?
Mule deer in an area with a mountain lion population.......good luck getting within 200 yards!!!!!
I would have to respectfully disagree on the coyotes (out west at least)......if you set up right (up wind, good cover, shooting lanes, etc.) they are relatively easy call in and to take with a bow (plus there are a BUNCH of them around here). My hunting partner and I kill 3 or 4 a year during archery mule deer season.
