I'm a big fan of the can calls. In my experience, they are the only type of deer calls that work.... I'm sure if our buck:doe ratio was more like it is in the mid-west or Texas then rattling and grunting may produce better results... but in my part of the world.. you are just making noise. Can calls seem to work well when you have spotted the deer already and are just trying to steer them your way. I've had several deer come my direction to investigate.
