Keep Out

I found it funny that all national parks have barbed-wire fences that define their boundaries when one of the park service's primary goals is to provide for the recooperation and survival of endangered species. Sure most animals can jump the fence or burrow under it, but I figure the last thing the service should be doing is contributing to the already extensive array of physical barriers the face migrating speceis. Like highways, home construction, poaching and a 40-year drought isn't enough.
