The North American ticket prices are just obscene. Looking at Ottawa, $349ca after Ticketmaster tax for one bleachers seat over half way back from the stage, $750ca for an actually decent (official) seat. You'd have to be a moron or a massochist to pay that. You could pretty near fly from Canada to Donington, see the show, and fly back for that money. This is not just supply and demand, it's an asymmetrical market place, artificial scarcity and a seller (sadly the band itself), prepared to gouge the very eyes out of their customers.
