I spend at least a good 5000 in concerts every year, on tickets alone.
Travel is a completely different category, in which I probably spend about a good 10000 a year.
I mean, but I'm a different case than most people because I follow bands/tours, and I just know that shit adds up if you're not careful.
For instance, I'm planning on doing at least 25 dates of Tori Amos' upcoming tour (no judgement), and I already know I need to save about 2000 for it. I just did the three Daft Punk dates across the country, which although it didn't set me back as much as 25 shows in 2 months, it still set me back a couple hundred.
But you just roll with it, I mean, it pays off in the end for me, anyway.
