Yankee Stadium
The House that Ruth Built: Surprisingly enough, Yankee Stadium in the Bronx has become one of the hottest bones of contention between the Camarilla and Sabbat. Many of the remaining Camarilla members in Manhattan are old enough to remember the glory days of Mantle and DiMaggio, or even those of Gehrig and Ruth, and the Stadium holds great sentimental value for them. The Sabbat, while having no particular attachment to the Stadium per se, simply wishes to deny access to Camarilla members, and so bloody battles are often fought merely for freedom to attend the odd night game with the Red Sox or Orioles.
The fact that Boston and Baltimore are the two other heavily contested cities in the East Coast megalopolis is completely coincidental, of course.
