It amazes me how spoiled you guys out west are when it comes to National Parks. There are already lots of National Parks out there, and they were created from Federal Government land at no cost to the western states. In order for us back east to have Shenandoah National Park, the state of Virginia had to buy the land and donate it to the Federal Government.
I guess it comes from that western attitude that says westerners should have the right to tell the Federal Government how to run its western property (without interference from easterners), even though it is owned by the wole country and was bought and paid for by easterners.
