I have been hunting by myself for 20+yrs, but the coolest thing I have ever seen was fishing with my dad in Canada. Fishing on the English river, there are a pair of bald eagles that my dad has 'trained' to come to him when he whistles. After he catches a northern pike that is legal length, he'll smack it's head and toss it in the water and whistle a couple of times. Within 5 mins, a bald eagle will swoop down and it's lunch time, often feeling the wind from their wings!!!
