Nice idea, I had a quick look at Google Earth and you can even spot that yellow switcher sitting there in the yard.
But actually the airport I have is much smaller having a single 3500ft runway only, intended for light aircraft mainly. The C-130 in those recent shots would hardly be a regular visitor, although it's takeoff distance is just good enough. The Constellation however would not have made it... I just felt like using that one for a nice shot.
So anything more than a single spur for fuel deliveries would be way over the top. Furthermore that area is pretty much done apart from detailing/ground texturing/vegetation and I have no intention to change all of it again, however I might be able to squeeze in said spur. I will think of it.
And no worries, there will be some interesting industries to serve elsewhere on the route.
Thanks for the input.
