re: Tiger Stadium Ticket Availability Map as of 9:15 PM

Out of curiosity, why isn't there an incredibly cheap ticket option? If they are really having this hard of a time selling tickets, why not offer a steal at $15-20 for upper deck tickets. I know the local community north of campus is usually not able to attend games due to prices. The Colorado Rockies have the Rock Pile section which has $4 tickets and is full just about every night of the week. I understand staffing concerns, but if these sections are already open and staffed, might as well fill it up and make some money.
