One more option. You are visiting or driving through and you witness an incident. You have no idea where you are but you know you need help. Find a box, pull the handles, BFD will be there in less than 3 minutes. Remember Boston had the first working box alarm system. KUDO to my late uncle Frank Mizer, worked at BFD FAO during their war years. Made a great spaghetti and meat ball dinner. At times he would call me and my first wife to go shopping for ingredients. After feeding the crew at FAO my wife and I ended up making deliveries to E33/L15 and E37/L26. Both houses invited us to eat with them.
