I think the only people saying we should choose another bowl to "broaden our horizons" are those simply trying to poo poo on our accomplishment of winning the NOLA bowl four straight years.
If Miami won the Orange Bowl 4 years in a row, UCLA the Rose, LSU the Sugar, etc then those teams would be considered some of the greatest teams ever. I'm not saying the Cajuns are the greatest ever, simply stating that the perceived home game of playing in NOLA does not diminish our success in the last four seasons.
Only reason I'd like the Cajuns to play in a different bowl would be to make it easier for me to attend, anyway, West Virginia doesn't host a bowl so there goes that!
