How much does extraction by a national guard helicopter really cost? They already own it. They are already paying the guys who are flying it. It will incur some wear and tear during the time it is aloft and use some fuel. That is a pretty minor cost compared even to what that person will pay in sales tax during the remainder of his life.

Consider also that most of the money that goes to maintain public areas comes from people that never use them. Should each park be required to finance its entire operation solely from the revenues it generates? Where do you draw the line? If S&R becomes something that you have to pay extra for, does that mean you can sue them for not providing a specific level of service?

I really think that the Law of Unintended Consequences will really make several unwanted appearances if we head too far down this path.
