... and a corollary: If one does *NOT* do a popup, but rather files IFR
and departs VFR, how much of a hassle is it to open said flight plan
mid-stream? Picking up a flight plan filed with a different FSS for
departure
3 hours earlier is not likely to work and will degenerate into a popup.


Do you mean filing IFR from an untowered field and calling for clearance
shortly after departure? That usually works quite well as it is actually
easier for the controller.
