Best Climbing Experience

My first big sport multipitch. Via Cinquantenario GAM, Sas Ciampac overlooking Corvara. I'd climbed maybe 4 times outdoors in the past two years, and was more than a little uncertain of my ability to lead 6b, nevermind complete 17 pitches of climbing. 10 hours, some major runouts, and some routefinding issues later, we summited. I didn't feel that elated until much later, as I was too damn tired!
