The Fire TGs in the RR database are outdated as far as order goes. A while back, Spring Hill FR was dispatched on Fire-1, and the rest of the county was dispatched on Fire-5. Some restructuring took place (as far as who dispatches who) and the TGs changed order. My above post is from info posted somewhere (I think is was on a local email list) by a Hernando local, and is accurate AFAIK, but I have not confirmed them all. I do know that Fire-1 and Fire-2 as posted above are good.
The 60928 TG you referenced is a Mutual Aid type TG, and is not a typical Fire/Rescue TG.
