Ruffeds will be mostly where there is moisture and dense hardwoods - riparian bottoms, clearcuts with willow/hazel/aspen/alder/cherry regrowth. They also tend to go to roads for gravel in the early evening. Best way to find blues is drive up and down in elevation until you find a brood, then hunt that elevation band to +500'-1000' elevation, especially along the edge of timber and grassy openings. Remember that elevation, because next time you'll start there and look higher (they migrate up in the fall, eventually wintering in mature conifers, especially Douglas fir, at high elevations).
