N'Sync!!!!
Sarah Evans/Lonestar
Trace Adkins (years ago when I was in Jr High)
KENNY CHESNEY! (my favorite!!!) - with Sugarland, Miranda Lambert (my guy has a crush on her so I was kind of indifferent about this lol), Lady Antebellum, Gary Allen & Montgomery Gentry one year.... He also played an impromptu show standing on a boat on the edge of the River by Hienz field during the day before the show... another year w/ him I saw Keith Urban & LeAnn Rimes
If anything go see Kenny. He is AMAZING & I was really sad there was no tour this year.
DAUGHTRY! Loved this. We were 3rd Row but up against the walk out stage for a $20 ticket (love student prices)
Brad Paisley, Dierks Bentley & Jimmy Wayne (who I also saw a few years ago at Longaberger when he was first getting going)
On my list this fall is Carrie Underwood bc she is going to PSU! I still have to get tickets though!
That's all I can think of right now. I love concerts though
