Seriously? The NRA hasn't done enough damage to our country that they now want to hunt and fish in our national parks? These areas are set aside for habitat preservation and to protect scenic areas for the public. They aren't like the national forests, which are multi-use. (Yes, there is some hunting and fishing in parks, but it's very limited.)
While we're at it, why not do a little logging in the parks as well? Some of them have just too many trees. I'm pretty sure we can find some super oil and gas deposits too. Perhaps a little strip mining?
Yes, I'm exaggerating, but it's a slippery slope. The parks are either protected or they're not.
