BISMARCK, North Dakota (AP) -- With a shortage of flu vaccine across the country, Margaret Holmen and others from the Powers Lake Senior Citizens Center have been talking about going to Canada for their shots.

Clinics and pharmacies across the border are offering to inoculate U.S. residents, and Holmen said she planned to call clinics in Estevan, Saskatchewan, if she cannot get a flu shot in North Dakota this week.

Urgent Care Niagara's Fort Erie clinic, just across the border from Buffalo, said it would vaccinate 100 Americans a day, for around $40 U.S. each, squeezing them in among Canadian patients who got first priority.

Virginia Matysiak was No. 100. She and her son Kenneth picked up the number after waiting in line then killed time at the nearby Fort Erie Race Track and Slots. "We ate lunch and played and came back" -- $100 richer, she said.
