| 2005 | Toronto, ON | "No more out of the country trips" |
| 2006 | Chicago, IL | Too busy |
| 2007 | Housten, TX | Too busy and Summer in Texas?! |
| 2008 | Chicago, IL | Too busy |
| 2009 | Pittsburg, PA | Way too busy - really wanted to go to 10th Annversary |
| 2014 | Orlando, FL | Way too busy again. Watched Live instead. |
