The granite falls/outer snohomish area is a "hot spot" for wackos. A couple years ago i parked my truck on a nice sunny day above Granite and was working my way downstream fishing all the pockets and small pools, when about a mile of river later i came around a bend and saw a guy laying on a sand bar about 50 yards away. I kept fishing while keeping an eye on the guy when out of the corner of my eye he raises his arm and exposes a machette commonly used to cut brush. I took two more casts and slowly walked upriver and when he was out of site i took off at a "fast pace" all the way back to my truck.
I rarely fish the river anymore, mostly due to increased pressure and the very obvious downward trend in fish numbers. Be careful out there!
