In 2002 my ticket was 250 pesos (around 20 dollars) but, since I got it from "reventa" (I don't remember the english for "reventa", I mean when someone buys a ticket for the real price and then he sells it for a much higher price, ilegally, of course, very common here in Mexico) I paid 900 pesos (about 70 USdlls) and it was the worst seats, last rows in a 20 000 people arena and I was mainly watching Paul's back all the time, had no view of the screens...but come on! It was Paul McCartney! It was all worth it.
Last February I was luckier. Went to see Keane at the same arena and I was at 100m from the band, watching from the front, good seats actually, I paid 1250 pesos, about 96 US dlls.
We can make it to Mexico City...AGAIN!!!!!
