Months mentioned are the height of the Winter fishing on the upper Rogue River. Tonne of public access; if you decide to come this way I'll tell you 'what rock' to stand on.
Can't assure there will fish in front of you, but you'll know about access. Do I sound like a hero/big mouth? Not in the least. The upper Rogue has close to 60 miles of river and the fishing pressure (there are a few exceptions) is light especially during the week. No one will even know you're there.
Last out/spots I saw a grand total of three other fishermen.
