While attending the annual USNA vs. St. Johns College croquet match last Saturday, a fire broke out in a wall between 2 businesses on Maryland Ave. Since I was nearby, I walked down to the scene where I noticed 2 AA Co. units that I have never seen before. One was an unmarked Stratus, the other was an unmarked Honda (or similar Japanese) sedan. Both were equipped with emergency lights, and the personnel who departed the cars were wearing blue working uniforms with AA Co. Fire Dept. patches. Anybody know who / what theses units were? I suspect they might have been FM's, or possibly PA.
