I have only done it once and can really only engage in it for a few months each year; mushroom picking. In particular psilocybin containing mushrooms. Last year I went out at night while it was raining around the neighborhood and to parks scouring the ground for mushrooms. I found plenty but none of the variety that I was searching for (Psilocybe subaeruginosa). Nevertheless I had a wonderful time. It was also a great tool to combat social anxiety. I was essentially snooping around in bushes in the dark all alone. At one point while I was in a bush on all fours examining the ground a couple walking past saw me and shined a torch at me before promptly walking off.
