Only North and East exist. North consists of Black Forest, Wescott, Tri-Lakes, Palmer Lake, Larkspur, AFA and Falcon (Falcon responds with North Group only if it's in Black Forest). East consists of Ellicott, Hanover, Tri-County, Edison and Colorado Springs Utilities (wildland fires only).I heard of a North Group for automatic mutual aid. Are there any others? East? South? West? Who belongs to which?
