How about someplace west of Pennsylvania? California, anyone? Skyliner's (Garbarina) went to AL in Los Angeles in 1950; & it was a lot harder (& I bet more expensive in standardized $$) back then to travel. I'm sure there were other examples. Renegades suck it up and come east, sometimes > once/season, & I know aircraft fly both directions.
Racine is good too, how about St Paul? Dallas?
