How many folks are going to give up their tickets out of principle? Not too many, I'd guess, when that principle is only set against a buck a seat.
See Thunder's post above. He'll pay the extra dollar and he doesn't even like being there.
I hear you, though. That is the society that we live in right now--nickel and diming. I complained a lot when the airlines started charging for luggage, but I haven't stepped foot on an Amtrack train yet. I live about 18 hours away from Iowa City by car, so I have no dog in this particular fight, but I understand how it can be frustrating.
At the end of the day, Barta has read the cards right, because even for those whose budget is stretched by the ticket prices, $1/game is a reallocation from other entertainment budget, not a fish-or-cut-bait increase. Most folks, if given the predicament would skimp on their kids' stocking stuffers and keep the tickets.
