As reported by Dr Gridlock,
Alexandria transportation officials are considering a $400,000 pilot program with Capital Bikeshare, the regional bike-sharing network started by Arlington County and the District in September.
The King Street Metro is the no-brainer locale as astutely noted by this commenter at GGW.
Being able to grab a bike at King Street station and riding it east to the heart of Old Town would be fantastic. Often the mile is a little far to walk (especially when you're in a rush) but taking a cab or bus is often impractical. Bike share solves that problem immediately!

The King Street Trolley is also available.
