BRIMSON (AP) - Worried about wolves becoming too bold around humans, Minnesota wildlife officials are stepping up warnings to people not to feed the animals increasingly wandering along northeastern Minnesota roadways.

The campaign has taken on special significance north of Duluth, where tourists are looking to catch glimpses of wolf pups sometimes by leaving food on the roadside. The pups have readily approached vehicles Minnesota Public Radio News (http://bit.ly/151xWvh ) reported Friday.

Assistant Department of Natural Resources wildlife manager Nancy Hansen says the pups use the stretch of forest near the intersection of two county highways as a rendezvous site while adults in the pack leave to hunt. She says officials cannot relocate the pups, because they would either die away from the pack or just return to the area.
