RE: Who uses their harness while climbing?
I realize that most of us are getting old in age (I'm still 18 in spunk), but in climbing a tree, I now have a fresh memory. My son who is 7, climbs until he is to the very very top. As much as a dad who doesn't want to see my son hurt or dead, all I can say is be very carefull and watch out for the (blank). I climbed like that in my memory as if it was yesterday.
Rule number one you will die. You know your boundries. Be safe.
