So how many fishermen have you talked to? My impression from speaking to at least one (former) fishing boat captain is that the problem with the fishing industry is that they're running out of fish. Fishermen from the Chesapeake Bay have gone as far as the Gulf of Mexico to fish. It's not rocket science.
It is possible for federal lands to be well managed, be they national parks, national forests or range lands. In theory, it is equally possible for state lands to be well managed, too. Naturally, there are competing interests and apparently no one wants to actually bear any of the costs. The anti-socialist element would privatize all such places, no doubt. Hunting and fishing is only one of the uses of federal lands and it probably isn't the largest. I suspect that much of the hatred directed at federal land managers is because of the simple fact that some people can't do whatever they want, whenever they want, where ever they want to do it. How'd you like to be a forest ranger, huh?
Rich people do their hunting on private lands anyway.
Shoot low, sheriff. They're riding Shetlands!
Underneath the starry flag, civilize 'em with a Krag,
and return us to our own beloved homes!
