I see USAF UH-1N Twin Hueys all the time. They fly over my home enroute to the Selkirk Mountains, where they support Air Force Survival School training.
Last year I was out walking the dog and one flew over (I live a 1/2 mile east of US Hwy 2, their preferred route) and waved. He did a circle over me in acknowledgement. Another time I was on the highway, and the ceiling was getting low. I hear the "whop, whop", very loudly. I look through the sunroof and above me is the unmistakable shape of a Huey....making a beeline to Fairchild before the weather really closed in.
Aside from the Sheriff's surplus OH-58 (modified at great expense with all the IR cop stuff...much to the chagrin of the local anti-police crowd) and the Border Patrol's AStar, it's the only government helicopter around so it does a fair amount of SAR. Of the AF's 79 N models bought in 1971, the survivors are doing this and missile site support, since their long standing role in special ops has been replace by Pave Hawks. They're probably some of the oldest helicopters in US military service now that the Navy has retired the CH-46s. Some Army CH-47s are also old, but the original 60s airframes have been rebuilt a time or two (from A/B/Cs to Ds then again Fs) and have different serials.
