So many that I REALLY like.
For breakthrough grade, got to be my very first .10 (sport) on-sight; Green Piece (not Peace), Butchers, NRG, 20 years ago this Fall.
Satisfaction wise, flash of Sancho Belige (two or three routes over from Green Piece) and, in the process, winning a six-pack from Whitey, without whom I would not have tried so hard.
Only one, John? Not sure why to where to place my first Gunks .8, .9, and .10. I am so conflicted
