Yikes on these prices!
When I was in college -ahem, a while ago - I saw Springsteen during his Born in the USA tour on campus for $25, 20 rows back on the floor. Same with U2 Joshua Tree tour. I saw Don Henley solo, James Taylor and the BoDeans over the next couple years, nothing over $40 (because I was a poor recent grad).
When my nieces told me what they paid for Taylor Swift tickets, I died.
