Coues deer with a bow, while not impossible, is very challenging. Elk during the rut is constant close encounters and action. Not sure where you are from, but coues deer are no joke. The terrain is rugged and unforgiving....Rocky, steep, everything has thorns too! They are a tough trophy with any weapon. Plan on many hours of hiking and glassing. Best to be on your A game and have the best glass and boots you can afford.
