Pinus edulis produces great nuts, wonderful to eat. The problem is that they are readily harvestible in a very short window, IIRC, about a month long period during the fall (right now they should be abundant on the Colorado plateau). The rest of the year Pinus edulis is just a pretty tree. You are going to be competing with many other critters to bring in the harvest. I recall fondly one fall in Mesa Verde when I sought out and ate every pinyon nut I could find. The effort to collect and crack the nuts kept my waistline from expanding.
