I've seen them 3 times. I don't know if I'll see them again.
Back in the day (mid-late 90's and early 2000's) I went to so many concerts as I was in my late teens-early 20's then living in a major metropolitan area. There was a show or two to go to every week of the year and I dropped a lot of $$ on concert tickets from 1995-2002.
I've gotten older, married, kids, career, moved away, etc. and the desire to go to concerts has really become non-existent. I'm content with cranking up albums. Priorities change. We change.
I have fond memories of DT shows. All 3 that I saw were excellent.
