I know WMATA doesn't serve Prince William County or the Manassases (Manassi?), but it would be nice to see Omniride included at least as a connecting service on those maps to supplement VRE. Omniride buses take Smartrip fare cards, so it is definitely a valid connection IMO.
Especially with the silver line extended all the way past Dulles, provisions made to potentially extend the orange line in the future, and the promise of Long Bridge 2 with off peak and weekend VRE service, I think there is a growing role for an extension/supplemental service to the Omniride 96 line linking VRE stations in Woodbridge or Rippon, the existing Omniride Transit Center in Dale City, Manassas VRE station, Centreville and Chantilly Park and ride facilities with service to the Orange line terminus, and Dulles Airport to connect to the silver line. It's about twice as fast right now to get from Manassas to DCA as it is to get from Manassas to Dulles using transit, and that is just silly. Especially if Manassas is actually serious about building out it's own airport passenger service that could reasonably have connections through Dulles if the airports were at all accessible to each other without a car. But this map wouldn't even show that connection unless it was operated partially or wholly as a Fairfax Connector service, which feels a little silly
