Consider this: A ticket to Anchorage is about $250 RT. Rent a minivan (you can sleep in it) $450 for a week. Allow about another $400 for gas, grub and a lisence. Drive north and hit the Paxton Hwy and you can catch graying till you're sick of them. $1100. A little more than Montana, but not that much, and you're in Alaska! Or fly to Fairbanks instead and you can catch them right in town and stay in a hotel.
