I too can remember my first limbwalk .......... but I would have to say that one of my most memorable walks was a few years back during the SSA climbing competition held at TCI Expo Milwaukee.
For those who aren't familiar with competition rules, the climber must manouver/walk out to a pre-placed bell/marker, lanyard in, ring it, and return safely to decend, all without placing too much downward force on the limb, therefore, causing a hanging throwbag to touch the ground. As a result, climbers have to be resourceful and not just run out the limb, for if the bag touches the ground, points are deducted!
The following two pictures are different angle of me moreless walking horizontally to allow my force to be displaced side-to-side instead of downward. The tactic worked and I had a great time!
