I don't show Kanim in my book (it's an older one), so I can't comment on Spur 10. Where is the lake located?
Once you get to the Spur 10 gate, if you go left or right, you need a pass. If you head straight, you don't. Be advised that the Spur 10 gate is closed until 3:00 PM to public access. Those logging trucks really haul on those roads....
I'll check my other book and see where it is located.
