SEC Has Home field advantage in bowl games

I acknowledge that the SEC is the strongest conference in college football. However, we have no idea how big of a margin it is.

How many bcs bowl games have SEC teams won in the Sugar Bowl? LSU has never won a BCS game outside of the Superdome. Florida has only 1 BCS victory outside of the Sugar Bowl or the Orange Bowl, a stadium in their home state. Same for Georgia. Alabama did win in the Rose Bowl.

On a side note, USC is very successful in BCS games...as long as they are playing in the Rose Bowl. My point is that the SEC wins--a lot--in BCS games. How much of that is due to where the game is played?

PS-Teams from the Big Ten, the SEC fans' frequent targets, never get to play in their home stadium or state for a bowl game. However, Ohio State has a strong reputation for traveling well (probably why they have played more BCS games than anyone). They are 6-3 in BCS games, probably due to having more fans in the seats than the opposition most of the time, aka a "home field advantage" of sorts.
