salt is legal in mn too. i've had a salt lick in the same spot for about 8 years now. it's behind one of my stands. I've had deer go to it two times while hunting and that is a stand i've hunted more then any other stand. the lick gets lots of use just during the spring, summer and early fall. they pretty much leave it alone starting the week before bow hunting [:@].

also, i've got literally hundreds of pictures of deer at my salt lick. but only one nice buck (in the 3 years i've had a camera). it was a really nice 11 point in august. never during the hunting season.

i guess what i'm saying is don't pin your hopes on salt because you will be dissapointed.
