Turning onto a two-track, we drove in a quarter mile, stopped and stepped outside the truck just to stand and listen. Drizzle dripped and in under two minutes a bull screamed from over half a mile upslope. We grabbed our gear and hustled up the two-track about 300 yards and then veered off to the west. The screams and bugles, which were being launched every two minutes or so, gradually distancing us. Soft pursuit time! Finally, after 10 minutes of pussyfooting toward the animals, we saw some of the harem through the lodgepoles and conifers.
