I'm not a scanner person at all so I don't speak the language. I used to report so long ago I had to go to the stations and read paper. When I picture these areas, it's the map I see, of course and the central glue is West Metro Fire.
As someone without a scanner, I use the web and the phone app, so my response is from that market. If I were looking for those jurisdictions, I'd probably stop at West Metro. The only city police/fire missing from that is Golden. Intuitively, I'd expect that as part of the package. Not finding it in there, I'd search further, of course, and find it as a stand-alone.
If I'm way off base for you expert guys, please don't shoot me. My SO won't know which feed to go to find the calls.
