Here's my advice, which you need to take with a grain of salt, I have yet to harvest a turkey.
Get to a place the you KNOW holds birds, meaning, get over to Stevens County. Before you go, pull out a map and start identifying huntable areas. Leave work early on a Friday, scout/hunt all weekend, start learning the areas you ID'd in the previous exercise. It doesn't guarantee you a bird, but I'll tell you what, your odds will be much greater in Stevens County than in any other area of the state, especially if you've never turkey hunted.
