Makes sense. Yeah, just didn’t seem like the type of place I’d be comfortable fishing without explicit landowner permission. And to fish any measurable stretch of it, you’d need permission from lots of different landowners. Only takes one po’d landowner to hassle you or call the authorities as you’re fishing up through, and you’d be crossing property lines nearly constantly.
(I don’t fish privately owned, but unposted water without permission anyway, unless it’s obvious…STW/Fishing Permitted signs, etc. Personal choice, and not judging anyone who does it different, but legally.)
