pine nuts

When we had buffet lunch in a hotel, we noticed the garnishings of the steak. We usually buy pine nut when we go abroad particularly in Hongkong where it is cheaper. There was pine nut. That's the favorite nut of my husband. Until now we still don't know where that nut comes from. Is it really...

Hey everyone, this is kind of a weird question, but does anyone know how you go about extracting/collecting pine nuts? I really love them, especially in my summer cooking, but even a little package of them can be pricey. Does anyone collect the nuts themselves or have advice for doing so? Thanks! :)
