The presidential primaries for Virginia, Maryland, and DC will be held this coming Tuesday the 12th. This is kind of a big deal. These are open primaries, which means it doesn't matter what party you're affiliated with. So there are no excuses. The polling places will be the same as the last election, and the polls open at 7am.
Primaries are confusing, so there's a pretty good FAQ
here.
On a personal note, this will be my first presidential primary. In 2004 everything was all wrapped up by the time things got around to Virginia. And I considered myself to be more of a libertarian back then anyways. [The internet makes libertarians look retarded. I don't want to abolish the FDA. Also I was only 19 at the time so I didn't know any better. Damnit.]
