A blind man can find turkeys in the NE corner of the state. There is plenty of state land and the Little Pend O' Wildlife Area. Go to
www.mapmet.com and find a spot. Or contact the DNR Office in Colville for a map. Get off the main roads and ask some land owners for private land access. Read past threads on this site.
Go to wdfw hunt under regulations and pull up the spring turkey regs and look at the distribution map which will give an idea, then find the creek drainages and burn some shoe leather. This is a good time of the year to do that ....
Visit the Oregon Department orf Game website for out of state turkey hunting info. I think the best Oregon hunting is down towards Roseburg and south.
Attend a turkey hunting seminar.
Good luck ....
