Anywhere where there is found to be fossil fuel supply like oil or gas or even coal should be open to exploration and eventually drilling. Even thought this land may be a national park the drilling should commence. Since the find is on Government land the proceeds should go to reduce the national debt.
People are trying to enjoy there time in a park and the last thing i want to see is a giant oil rig in a field. It ruins the taste of the park and it can be harm full to people and the animals of the park. Don't do it!
