Why in the world does he need a TFR established wherever he decides to go?
Tis common practice for the POTUS and the VP. Some of the fun ones were when Dick Cheney would go fishing in his drift boat on the Snake River. His property in Jackson Hole lies on the border of two National Forests. The TFR would be a "Rolling TFR"--speed determined by the water flow and where he took lunch. I was on fire contract on those forestswith a helicopter for his last 3 years in office.
In reality the Secret Service is easy to work with. We had a discrete transponder code and direct phone and radio communication with them in the event we needed to get in and effect an initial attack on a wild fire.
