I had the pleasure many years ago of going out with a close friend of mine and his wife to hunt for morelle mushrooms. They were experts. This was a real eye-opening experience for me. I learned so much this way in an extremely short amount of time: when to look, optimum locations, types of trees to look near, and exactly where to look. I found dozens' of 'em within 30 mins to an hour, whereas in the previous 40 years of my life in similar environments, I hadn't seen a single one.
