I've been going back through concert tickets before 2008 (when i started using the woxy boards list) and putting together one comprehensive list. I wonder how many tickets I've lost and how many show didn't have tickets.
If you are referring to concert ticket cellecting, let me tell you. I have ALL of my concert tickets from when I arrived in the US in 1983. Yea. Stacks and stacks.
Always hated it that the SGH didn't have 'real' tickets for their shows (and hence no "proof" or remembrance that I was at, say, the Strokes in 2001 or Interpol in 2003). <sigh>
Even worse is that I lost my ENTIRE concert ticket collection from growing up in Belgium. I still to this day do not know what happened to that. I suspect my parents threw them out at some point. Those were the days when many concert tickets were really cool "designer" tickets. So I lost my concert tickets of Queen, Led Zeppelin, and many, many others. ARGH!
