It does seem that with all the predator hunters calling wolves etc., that a bear would show up once in a while. I have never seen it or heard of it though.
There are a lot of area's where spot and stalk just don't work, and calling one in is a slim to none chance also.
Wow. You guys are missing out. Bears slobbering, jaw popping, grabing branches and running or sneaking in. Been doing it over a dozen years and called in over 2 dozen black bears in WA. They ranged in size from 150 lbs to over 400.
