I'm sure that this has been addressed before, but was curious...I just read that the reason for the 11 in Chicago Fire's response of 2-11, 3-11, etc. is because "11 apparatus are sent." Is this true, or was the 11 more a result of trying to get everyone else's attention in the days of the fire bell signals? I'm just curious, as I haven't been able to find a solid answer.
Thanks!
Thanks!
