text: Clearly I know considerably more about bears than you do (and wildlife in general).  The bear "announced itself" with growls and huffing characteristic of Ursus arctos.  Black bears sound different.  The bear shadowed me because it wanted me out of its foraging grounds instead of attacking me without warning, as it would have done had it been interested in killing and eating me.  For which I am thankful.
  
  Instead it followed me for a half hour until I got to my car.  I was fortunate.  My hind-brain kept screaming for me to RUN!  But I knew better than to let a bear see me run.  Apparently you don't.  
  
  And in my time in Alaska I have probably encountered in excess of 50 coastal brown bears and a smaller number of black bears (can you say the same?). Once including a sow with three cubs which swatted the water-surface of a stream she was crossing to let me know I shouldn't be where I was when she got there.  I agreed.  On your little trike-trail you'd have never seen her coming.
