I know Clint KB6CLA is a big proponent of 220 Mhz in general, and Condor in particular. He is usually on the Blue Ridge or Frost Peak 220 Mhz machine.
I think Ron KI6SLK is also working 220 regularly. I don't have 220 in the vehicles, just on HTs, so I only work them from home (when I actually am home...).
