The encounters I have had with black bears have all been either seeing their south end going north or just curious appraisal. I have seen Grizzly tracks in the local mountains, FWP says a lone sow has had a den with cubs every year for the last 5. For some reason their genius spokesman was unable to explain how a lone sow was getting pregnant nor where her cubs were going.
Only grizzly sightings were in National Parks where they recognized they were Divas.
