Challenge, Double Creek??? Methinks that's a matter of low importance in today's bowhunting world. 300 fps bows, carbon arrows, mechanical releases, mechanical heads, scent blocking this and that, treestands, camo to match each and every tree and bush in the forest, calls, scents, decoys, gps, radio communications, lazer rangefinders, aerial maps... the list goes on and on and on! ALL these things are for one purpose - to reduce the amount of challenge in taking an animal with a bow and arrow and stack as many odds as possible in the lap of the bowhunter.

Automatic feeders are a very nice fit into modern bowhunting equipment and theory.
