RFK
From DCFanguide
Robert F. Kennedy Stadium (originally DC Stadium) was opened in 1960 as the home of the original baseball Senators and the football Redskins. This is the original dual-purpose, double-deck stadium that was planned to host both sports from day one.
To allow this, the third-base seats roll into left field to become the "loud side" seats for soccer. The permanent first-base side seats are known as the "quiet side." Hand-assembled bleachers exist to fill in the lower bowl, but these are not routinely used due to the rapid turnaround concurrent seasons require. Expect to see these for MLS Cup '07 but not until.
The return of baseball in 2005 has required compromise on all sides. The DC Stadium Authority has installed an elevator for the pitcher's mound and developed a system to install sod over the dirt infield of the baseball diamond. This patchwork sod is clearly visible and sometimes affects play by creating bad bounces.
There are six seating levels. The 100, 200, and 300 level seats form the lower bowl, collectively accommodating about 18000 for soccer. The 400 and 500 levels form the upper bowl. Typically seats are only sold in a few of the 400-level sections. Addition premium seating exists in the Mezzanine level between the 300 and 400 levels.
Entry to the stadium is at the top of the 200 level except for the Gate A, which is at the top of the 300 level.
DC United are not the first team to use RFK Stadium for the world's game. The North American Soccer League's Washington Whips (1967-1968), Washington Diplomats (1974-1981) and Team America (1983) all played in RFK for some or all of their existence. Additionally, RFK has hosted games during the 1994 World Cup, 1996 Atlanta Olympics, and 1999 Women's World Cup. The US Men's National Team was a regular visitor until the arrival of baseball.
