The Blue Pack is the conglomerate of the wolves imported from 1989-1991 during that phase of the repopulation project. They are the largest pack of true wolves, and maintain a wary truce with the Green Pack, as long as they each stay on their own side of the Service Road. _All_ adults of this pack are radio-implanted. Only a few odd cubs who haven't been sick yet are free of implants. The Blue Pack claims the forests south of the road and out past the southern border as its own.
