Engine 2:  Back in the late 1970s, early 1980s, I had Hollis, NH in my scanner. At that time  Hollis and Milford, NH were on the same frequency. Mont Vernon is dispatched  by Milford. On my scanner Hollis came in loud and clear but I could not  pick up Milford's dispatches. However, due to Mont Vernon's location on top of  the hill, I could pick up Mont Vernon FD's mobiles. I would not hear the dispatch  but I could hear Mont Vernon clearly. One night I was listening when I heard  "563 responding" (the '48 Mack was Engine 563),then "563 on the scene", etc. I   thought that it was unusual not to hear the first out engines 561 or 562.   Apparently, the call was minor because 563 returned shortly. End of story.  A week or so later I was reading the local paper and in the Mont Vernon news there  was a little article about the MVFD having had some apparatus problems. The article  mentioned that recently there had been a fire call and only one engine was  available to respond. I thought back to the night that I had heard 563 only  responding and I guessed that was the answer to my question. I'm not 100% sure that  it was referring to the same call that I heard but I believe that it was.  Moral of the story: Nothing stopped the rugged little "Type 45", whether it was on  duty in Billerica or Mont Vernon.
