I'm a bit of of a lazy bugger so climbing hills was never very close to the top of my "to do"list.
Back when I was a teenager, after reading about climbing Mount McKinaly (now known as Denali), I wanted to get into climbing. Never however made it very far. Highest assent I have made is about 7,000 feet, and highest altitude I climbed to was 13,642 feet although in that case I cheated and took the first 11,332 feet by cog railway.
