Okay, here's what I was able to grab off the Beaumont central site, control channel 854.3625:

38768 (P25) - Unknown, didn't hear much
11184 - public works, new talkgroup?
5040 - heard a couple of keyups.
I did not hear fire dispatches from Nederland, Port Neches, or Water District 10. All were primary users of ShareNet. I'm sure they're there, I just didn't catch them. Additionally I did not hear any patching between VHF fire channels in Hardin County (Lumberton, Batson, and one of the ESDs specifically) and this system.
I ran a control channel search from 851.0 to 860.9875 and heard neither the West Beaumont or Winnie site control channels where I could previously hear them. Conversely I didn't hear any new A93A control channels. I did drive past the Winnie site on 73 near Boondocks Road and saw techs working on it.
