I've discovered that I learn the most from an unusual place. The threads here are wonderful. However the biggest piece of insight for me typically comes when the thread has taken a serious left turn off subject (posters go bushwhaking).
Examples: I never considered layering down under rain gear a bad idea. I had never done it. I would consider only doing it with a poncho after reading about the "sauna" it can create. This was in a thread that was talking about a specific type of raingear. Not exactly entirely off subject, but a useful nugget none the less.
What piece of gold did you find in a most unusual place (and if you remember, where was it)?
