i know what you mean. im 6'3" and 170 lbs. low body fat. i went to my trainer and he said, "man, you have a perfect climbing body". to which i replied, "thats exactly why im here, im sick of people saying that". he chuckled.
It makes my third leg look a mile long because it is a mile long. Well, used to be. Used to get caught up in my chainrings if I didn't tuck it in my sock.
I remember one time I was riding down the road and I saw a rodeo cowboy trying to rope some doggies and I showed him what was up right there from the saddle of my trusty Schwinn Varsity. Of course, that was in my younger days, before the chainsaw accident. Now it's a bit shorter but it gets the job done. It's only as long as my arm, not my leg anymore. Can't feel much since that day I was cutting down a sturdy old oak tree out in front of my double wide, but that's a question for a different forum.
