The fun of Congressional Cemetery isn't the dead congressmen. The people buried here include D.C. scallywags, civil rights heroes, and at least one man killed by a tiger. As they say: "You don’t have to be famous to be buried here -- just dead." You might find a festival, a foot race or an outdoor movie underway, and certainly dogs at play. Your guide is a public radio reporter and a dues-paying member of the cemetery's innovative dog-walking club. The cemetery is open dawn to dusk daily. (Dogs admitted by membership only. If you hate dogs, come on Saturdays 11-3pm, when even member dogs aren't allowed.)
