The other day i was up in acer and had already topped it. With just the stalk left, I had only to block cut the remaining stalk which was about 50'. As I was lowering myself to the next cut, I had this deep fear inside me. Started to get a bit dizzy and tightened my saftey strap around the trunk. I have done this many times and have never had any feeling like this before, even when i wasn't properly tied in. Anyone had this before? Or am I just turning into a wuss? I love climbing.
