The best charter I ever did was to chase a snow train....in my case, the White Pass Rotary. The railroad provided a chartered, diesel-powered train to transport us to the job site, but almost nothing the crews did was specifically for the cameras. We paid only for the chase train, not the operation itself. That was funded by the railroad and was a real, no-kidding, line-clearing operation. The train just gave us access to the wilderness areas, so we could document what was going on. Of course, the rotary moved at a relatively slow pace and was pretty easy to "chase" on snowshoes. A flanger run would typically go much faster and be much more difficult to follow with a charter unless you could chase by car, as Jerry obviously did. Chasing by train would mean starting and stopping frequently, not to mention lots of slogging through hip-deep snow to get out ahead of the train without leaving a ton of footprints in the snow ahead of the train. I can tell you from experience that's not much fun, particularly up at altitude.
Jerry definitely scored. He even had snow falling. The only thing better would be chartering a Bell 206 Jet Ranger or something like it.
