I agree that extending metro by adding even more park-and-ride stations in the I-66 median is not desirable.

I could definitely see some Metro expansion in the district and Arlington, as well as the built up areas of Fairfax, Montgomery, and Prince George's counties, but simple extensions of the existing lines further into the suburbs is a bad idea.

There are plenty of dense areas much closer in that could use more transit. That would generate way more ridership and smart growth per dollar than running Metro further down the I-66 median to Centreville.
