I wouldn't go to my stand without a grunt and bleat can. If anyone is interested in tagging a doe early in the season the fawn bleat is the way to go. For bucks, I agree, using a young buck grunt is also the way to go. Also, two years back in Maine I starting using the bleat can along with the grunt tube. I did it one early morning during the rut and not 30 seconds later a doe came running out of a swamp with a nice buck on her tail. One grunt later the buck stopped and was mine. I would say, out of the last 10 deer I have shot 6 or 7 have been called in.
