I really hate it when friends visit & lose most of their hunt to bad weather but like Doc said, it happens. Two weeks later is ideal. I haven't been out since they left because it's never stopped raining or snowing or blowing until the last day or so.
Around the first of June at this elevation, 5700 ft in town is about the right time.
Today when my wife & I made a short drive to another little town we seen quite a few Chucks right along the highway. Maybe next time.
