I was feeling retrospective today and posted this thread in my buddy's facebook group The Metal Yard. Let me just say 2 things:
1) If you've been thinking about doing something like this and keep putting it off, just do it. You'll regret it if you don't.
2) Cherish your concert experiences, especially the rare ones. I saw Ozzy play Hammerjacks with Zakk Wylde as a warm up show for a tour and my only real memories were being 1st row and begging Ozzy to blast me with water because I was dying of cotton mouth and dehydration. Don't let this happen to you! hahaha
