Oops, my bad. I don't know why I got the two confused.
The one in "Home" is San Francisco Bay Stadium.
Candlestick Auditorium was never shown from the outside, so it really could be where Candlestick Park was.
(I do like the reference in Memory Beta about how cold and drafty the area around the auditorium is. 'Cause that sure as hell was true for Candlestick Park!)
