Ok i have a question that has been on my mind for some time. about 2 months ago a quint, 2 pumper trucks, and an ambulance, along with a battalion chief responded to call right across the street from me, the thing was the firefighters responded IN SCBA gear, after about ten minutes the engines , qunit, and battalion chief were still there but one pumper truck lef.t but later about 25 minutes into it the battalion chief, quint, and other pumper just left and drove around my naborhood for about 45 minutes before they dissapered. and while those three units drove around the ambulance just sat there with the emt's in it, in fact they never got out of it. Then five minutes after the 3 other units left the ambulance left. I would have asked but they were all focused on somthing and did not say anything to me. No one was removed from the house and there was no smoke. Could it have just been a slow night, also is the driving around the area normal. Any answer helps as i am VERY curious about this.
