Seen them twice in the past 10 years.  Were good shows.  Been trying to hit as many concerts as I can make it too, seems like a lot are hanging it up, going to concerts in the future when these guys all quit just won't cut it for me.  I'm going to try and make Bob Seger at the end of November, it's his last tour too.  I made it to Chicago/REO speedwagon, Foreigner/Whitesnake, and Def Leppard/Journey/Cheap Trick this year, which is already more concerts I've been too in one year, and Seger will make it  #4.  I've seen Reo, Cheap Trick twice, Journey 3X Def Leppard 5X.  Journey show wasn't as good as it was a few years ago, I think the new guy is losing his voice.  Def Leppard always put on a great show, but they need to change it up, it's always about the same songs in the same order.
