Not smarter, but I certainly have much more experience with bears of both types than you do. As for Colorado versus other locations, there may be some regional differences. Are you going to stake your life on those differences being major?
You did say that a man with a knife versus a black bear was almost a fair fight, if a grizzly attacks you're automatically dead...all of which seemed to indicate how you felt on the subject, and you were pretty definitive in your opinions - based on seeing one bear every three years. That pretty much added up to an epic information fail that would mislead others, therefore I responded.
If you only rode a motorcycle once every three years, would we credit your advice in that regard either?
