I met former Marine Sergeant the last adventure trip that my son and I went on to West Virginia.  He and his daughter were avid rock climbers and through discussion he discovered that we were going to be bouldering, but not rock climbing because we didn't have the gear to climb.  He immediately invited us to climb with he and his daughter the following day; we definitely took him up on it.  He let us use his gear and so I put the harness on, the shoes and then listened as he reminded me of how the carabiners and rope all worked.  I locked in and then looked at him and said "climbing" and he looked back at me and said "belaying".  I turned to the 70' wall, looked up at it to strategize on the path that I would take, lifted my foot and hand to the first foothold and handhold and off I went.
