I think the answer to number 2 is just the fact that it is spring and they are a little groggy from their deep sleep. I just killed a spring bear that a turkey hunter had seen one evening feeding on grass at 40 yards, he was able to take several pictures and leave the bear be. That evening he told me about it and I went there, sure enough it was there eating grass. Bearpaw led me to believe that it's fairly common for a bear fresh out of the den to be a little dumb, like its still trying to wake up.
