i know that in 2001 i spent close to $700 on concert tickets and cab fare-and those were all local shows! i gleefully told my coworkers that i couldn't afford vacation because i was going to see BDB, Travis, Dplan, U2, Madonna, etc etc etc. That music was my vacation. How f'n music geeky of me! HA!
but yeah, i too, have gone well into 4 digits. i think i'd rather just not tally the amount. so much for using that entry in microsoft money!
i will travel for shows. typically its just philly but a train ticket and hotel room is over $150 combined. and once you start going further-nyc, chicago, san fran, the price of your concert ticket was the cheapest thing!
it also depends on the artist touring that year. i know for prince, madonna, springsteen, u2, its going to cost $100 a ticket versus $15 for the frames. and if its u2, i'm going to see them multiple times on the tour.
