The forest service doesnt use spotter planes. Only Dnr. When the conditions present themselfs, the firebosses will make a lap or two looking for smokes in the Huron Manistee. Most of the time the DNR plane will spot it and call it into dispatch. Dispatch will then call it into forest service Cadillac Dispatch. Most of the USFS fire personal listen to the local departments and most of the time are enroute before their dispatch gets notified.
