Earlier quoted context omitted.
"the number of phish concerts you went to" Yep. For me it's "number of Mötley Crüe concerts attended" and "number of Trans-Siberian Orchestra concerts attended". (currently "4" and "4 or 5" respectively)
My wife and I have missed the Trans-Siberian Orchestra every year for 10 years, but we REALLY want to go. It's almost a running joke at this point. This year I set about a dozen alerts that'll start going off at the end of summer to make sure I don't forget to get the tickets.
I'm also very happy that they've slowly been incorporating more old Savatage songs into their sets. :-)
