We run out of Vienna, and here's every stop on the route, alphabetically, with the straight-line distance.
Arcola (15 mi), Belle Haven (14 mi), Bull Run (13 mi), Clifton (11 mi), Dunn Loring (2 mi), Falls Church (5 mi), Fort Belvoir (14 mi), Fort Hunt (16 mi), Great Falls (8 mi), Groveton (13 mi), Hybla Valley (14 mi), Lake Barcroft (6 mi), Manassas Park (13 mi), Mantua (3 mi), Mount Vernon (15 mi), Newington (12 mi), North Springfield (7 mi), Pimmit Hills (3 mi), Sudley (15 mi), Wakefield (5 mi), Wolf Trap (3 mi), and Yorkshire (13 mi).
We don't have a shop or crew based in any of these - we travel to each one from Vienna. The closer stops, Dunn Loring, Mantua, Pimmit Hills, and Wolf Trap, sit inside a three-mile ring and tend to fall into the same 1960s-70s housing wave described above, so the torsion-spring and roller failures repeat street to street. The far end of the list, Arcola, Sudley, Fort Hunt, and Yorkshire, run eleven to sixteen miles out, and a same-day call there depends more on where the truck already is that morning than on anything about the door itself.
