Are these common-sense concerns, or illegitimate fears? I would probably need more information about the location of the trail and the history of the area before making those assessments.
What opportunities in life do we miss because of fear? What calamities are we spared because of prudent caution? How do we find the proper balance?
Are you waiting for me to give you the answer to those questions? Don't hold your breath waiting for that. I am simply asking the questions.
