I wouldn't worry about it at all.Buy a bear tag and take your rifle.If you see someone parked at gate just park there and go on in,behind most gates there's plenty of land for a few hunters,see someone on a low road , then take the high road.
There are a lot of seasons that open up Sept 1, and more than enough woods for everybody,Go anytime you want on public land its there for everybody,not just bowhunters,you can be kinda good ,no target practice where you know someone is hunting,slaming truck doors,some things help,take a shotgun kill a few grouse and scout,i wouldn't even blink an eye about someone else hunting.
