I've never eaten them, but I met a guy who puts them in pot pie. He also said to take out the glands in the pits emmediately, and field dress them. He said if you soak them in salt water over night, it will draw out the remaining strong flavors.
Has anyone ever shot them out of trees? I haven't figured out why, but I've caught them napping a couple of times. Makes for an easy kill. They'll do this a lot in orchards and hedgerows between fields. once you spot them they're stuck, and the only way they can escape is by dropping out of the trees. If they're above 15 feet, I don't think they'll try this. They'll usually just stay really still, and hope you don't notice them
