On a different note. How many tours have you seen? Since I&W, I've seen every tour except the TOT tour. Both shows locally were on the weekend for that tour but in an odd twist, I had a weddington go to each time.
I&W (all three American legs)
Awake
ToT (the last leg where they opened for Yes)
Octavarium
SC (Chaos in Motion and Prog Nation '08)
BC&SL (prog Nation '09 and Final Frontier when they opened for Iron Maiden)
ADToE
DT12
I&W and Beyond
I cannot adequately explain how/why there is a near ten year gap. I saw them in December 1994, and the next shows in my area were in November 1997 and May 1998. Although I wasn't a fan of FII, I can think of no reason why I didn't attend those shows (I'm especially bummed that I missed the show with Ray Alder and Bruce Dickinson).
The next shows in my area were in February 2000, including the Los Angeles show that got shut down by the fire marshal. I was in my second year of law school, so maybe my excuse was that I didn't have the money (although I can't imagine that tickets -- especially at the Galaxy Theater in Santa Ana -- would have been all that expensive). Same with the second leg of the SFAM tour in August 2000, which was right at the start of my last year of law school.
The only tour I can think of a legit reason for missing is 6DOIT. They played in March and August 2002. My son was born in May 2002, and I was busting my ass as a first year associate. While I might have been able to get a pass for the show in March, there's no way I would have gotten one for the show in August.
The first leg of the ToT tour was right after my daughter was born, so I guess that's why I only saw the show where they opened for Yes.
