Commuter Biking (VA to DC)

Factual Questions
1

Does anyone bike from NOVA to DC? I am looking for a safe route from Falls Church, VA to DC.

2

Depending on where in Falls Church, I think either the W&OD to the Custis Trail or just the Custis Trail would be good. Custis follows 66 to Key Bridge.

Here are some useful pages:

Custis: http://bikewashington.org/trails/wad/custis.htm

Good luck!
