South Dakota is one of eight states in which people are allowed to buy tickets to Sunday's AFC Championship in Denver between the Broncos and New England Patriots. If you live in Iowa or Minnesota you are out of luck.

Tickets will only be sold people with a valid billing address in Colorado, New Mexico, Utah, Wyoming, Nebraska, Montana, South Dakota and Western Kansas.

Tickets go on sale at 11:00 A.M. Central time at Ticketmaster.com.

The Seattle Seahawks are restricting sales in the same way, but they are not allowing tickets to be sold to people in California. This is probably not a coincidence since the Seahawks are playing the San Francisco 49ers in Sunday's NFC Championship game.
