I live in Washington but often buy an Oregon license to build up my big game preference points. When I do I like to go squirrel hunting in Oregon. I've been going to the White River Wildlife area up by Mt Hood but the squirrels are far and few between these days. I'd like to try the Southern Oregon areas but am unfamiliar with that area.

Can someone point me to a likely area down there?

Allan, the area between Butte Falls and Prospect holds silver gray squirrels. Look for the zone in the Oregon hunting regs that has the most generous season. You don't want to be too far from oak habitat. Lots of wild hazel there, too. Good luck.
I have a .40 flint longrifle nearing completion that I would love to try on the rascals.
