They're everywhere. I know a couple guys getting picture after picture on the east side of Mille Lacs, my dad is up there rifle hunting as we speak, the week before opener they saw a pair as they were setting up tree stands. I called in a pair north of Kimball last year and ran across a few pairs of tracks just west of Monticello. A customer of mine showed me a wolf picture from a trail cam he set over a dead calf near Clearwater last year. My buddy lives between Big Lake and Elk River, a few miles south of Sand Dunes state forest and we hear them howling every once in a while nearly in the suburbs. I just talked to a buddy this morning about the wolves, he said a friend of his hears them around Zimmerman all the time.
It's a crap show, the north 2/3 of the state is full of them, maybe not the far west nearest the Dakotas, I dont get over there often.
