You're not that old. I was 15 then, but didn't go. Because I was 15 then. Ha! Saw them twice for Achtung Baby (ZooTV) and once each for the following tours. Just awesome. Favorite show was probably the All That You Can't Leave Behind tour because Garbage opened and they were my second-favorite band at the time. Plus we were about 5 feet off the point of the heart stage.
