Lived in NE OR for several years. Did very well in May where I was at. Hunt the recent burn scars, prescribed fire areas, and skid trails where logging or other mechanical thinning has been taking place. You can get this Intel from your local forest service district office. I found them more consistently in areas with Fir trees present. Other than the ticks, I miss the spring outdoor activities in Eastern Oregon big time! What a beautiful place to be this time of year. Good luck!Any tips for finding them in the blue mountains in NE Oregon?
