These resort channels are from last year; I don't know if they have changed with the sale of Killington/Pico by ASC. I had better notes but can't find them now.

Listen to VSP for local law enforcement.
460.150R 210.7 Killington repeater
460.475R 118.8 Knob repeater (Castleton-area)
Also, the Rutland Sheriff is on 460.450R 127.3.
Killington Fire is dispatched on 154.250/131.8. Their tactical channel is 154.310/D351, and they also license 154.175.
Regional EMS uses:
F-1 155.340S CSq Hospital Reports (one side, I think the mobile units, transmits 131.8)
F-2 155.280S 131.8 Transport Units Dispatch
F-3 154.540S D051 Non-Transport Units Dispatch
"The Bus" (Marble Valley Regional Transit System) is on an LTR system. 463.3875=LCN01, TGID=0-01-046. I heard little or no other traffic on this channel, so if you don't mind the idle bursts then programming it as conventional should be okay.
Some of the above information conflicts with what is elsewhere on the web. Since I only get up there once or twice per year, and have very little local knowledge, I won't promise that the above is accurate.
