From this story in the Billings Gazette
Officials with Montana Fish, Wildlife and Parks say hunters bought more than 2,000 wolf licenses within the first two days they were offered for sale. Officials said that license sales, whichstarted Monday, remained strong for the rest of the week in anticipation of the wolf hunting season that's scheduled to start in early September. Licenses cost $19 for residents and $350 for nonresidents. State wildlife commissioners last month approved a plan allowing hunters to shoot as many as 220 gray wolves. The hunt is expected to reduce the predator's Montana population by about 25 percent to 425 wolves.
