ZooTV - Vancouver II (November 1992) 35th row on the floor
PopMart - Edmonton I and II (June 1997) 6th and 8th row on the floor
Elevation - Toronto I and II, Montreal I and II, Buffalo (May 2001) Front row in the heart all 5 times - 4 times on Adam's side and one on Edge's.
ZooTV made me fall in love with UTEOTW - I wasn't a huge fan of this song and then it was so incredibly powerful and raw live that I cursed the fact I had underrated it for over a year! It was such a cool, dark, crazy and almost sinister atmosphere - very avant garde for a 19 year old girl from Central Alberta....
PopMart was fun, but for all the spectacle I barely remember it. Maybe it was because I was too annoyed I knew too many people at those concerts who weren't even U2 fans were at the concert. Grrrrrrr.
Elevation - what can I say, I saw the boys up close 5 times in two weeks. And I fulfilled my dream of being up against the barricade directly in front of Adam (4 times!

). So obviously this was my favorite tour ever. I also loved the fact that this tour was so toned down - no characters or theatrics. Other memories: Almost slapped a man who was in the heart and asked me "What side does the Edge usually stand on?" and got into an argument with Denise Richards.
And for the record, I prefer arenas.
