Soooo...with a little internet nooding I come up with this:
The landing on the trailer was in the town of Boulder Creek, California, which is in the mountains southwest of San Jose, CA. There's a big, empty construction lot just to the right of where the trailer is parked, which is obviously where the pilot dropped the chokers (or whatever the things were dangling on the end of the hook).
The a/c is owned by an operator in Biggs, California, which is 160 miles northeast of Boulder Creek. Problem is, if they wanted to fly home, a direct route would take them through the San Francisco/San Jose area, which is *highly* congested/populated, and UH-1H N194BP is a Restricted Category ship, which is problematic. So it's just easier to trailer it. And yeah, looks like that guy has done that landing a time or two before.
