I have started taking a Scott Bass Lession course called Fretboard Mastery". I came in feeling pretty good about my up the neck ability. Very soon I realized that outside C. G. D, F, my knowledge, outside of common grass and country notes, I was lost. Ask me to to hit a BB above the 9th fret and my reaction was a blank wall. Eventually, I could work out where BB is by finding A and figuring where BB was from there. Not very effective. I was completely enept from fret 9-12. After some effort, working three triad shapes the circle of fourths in three fretboard positions 1-5 5-9 and 9-12, I can now B find in a number places, including 9-12. Thanks Scott.
