I've landed 7 brats and 2 natives in 4 trips wading a small river where I only saw 2 other anglers over the 4 trips. Covered 2 to 4 miles of river each day. This is less than an hour from Seattle. So I say yes - you'll probably never see the name of this river featured in an article. You show somebody where to park and hike in half a mile to a great drift that's pretty much the only way they're going to find it - You know they'll show up fishing "your" drift with their neighbor and brother-in-law the next weekend - so you just don't tell him where you're catching your fish. Productive water with no people close to home is something you protect.
