Each time I visit a National Park, I am stuck by how much effort is made to undo a what seems like a correctable problem. Specifically, the threshold for entering a park is very low. Once inside the park, much effort is made to get visitors to be aware of dangers, to obey regulations related to plants and wildlife, to adhere to trail use recommendations--- essentially to behave in such a way that the park or visitor will not be injured or destroyed. Isn't this a backward approach to the problem? Imagine if this approach were used in regard to automobile or airplane operation, hunting, fishing, scuba diving, electrical or plumbing construction--- almost any other activity that has potential for error that can affect personal safety, injure others, or damage the environment. Given that many people are urbanized primarily and that many childhood outdoor educational opportunities such as Boy Scouts are less popular currently, it seems that some effort should be made to document a "threshold level of knowledge" prior to entry into a park or to provide a more organized indoctrination method.
Backcountry Permits exist primarily to educate backpackers about the proper behavior in the wilderness, why don't we have a similar process for "frontcountry" visitors? This process does not need to be cumbersome and could occur by an online process or procedure perhaps with renewal every 10 years or more. At the very least, every adult should agree by signature to a list of expected behaviors. This list could also serve to educate the visitor about the unique issues or dangers in a park by reading or listening to an organized recitation of important regulations or issues-- rattlesnakes, flash floods in slot canyons, cell phone function, stalactites, animal proximity, bear spray, etc (depending upon the park).
If individuals do not want to get out of their vehicles, fine-- no permit required.
The cure for a fallacious argument is a better argument, not the suppression of ideas.
