Well this is just a big ball of suck...
If you use Metro's Red Line to get to downtown from Glenmont through Fort Totten, things are going to be bad for a few weeks. The Capital Improvement Project is going to shut down the Red Line between Silver Spring and Fort Totten from 11/25 to 12/10. Bus service will be running so you can still get where you need to go, but make sure to allow plenty of extra time.
Hoo. Ray.
