What should I do with my extra nuts?

I have dozens of large, mature Black Walnut and Shagbark Hickory trees on my property. This is the season when they begin to drop nuts. The sound of hickory nuts hitting the roof of my metal pole barn sounds like .22 rifle fire. In fact my neighbor asked what I was shooting 24 hours per day.
I have been collecting about 2 pounds per day of hickory nuts because they are good to eat. But I already have well more than a year’s supply. The Black Walnuts are dropping full garbage cans full every day! I can go out an collect a 5 gallon bucket full in 3 minutes. They are messy and difficult to open so they are not desirable. I’ve already shot them out of my potato cannon, enjoyed batting practice, and golf driving practice with an old set of clubs. I shot at few and watched them explode. But all this does not make a dent in the supply.
Does anyone have any good ideas?
If you have similar trees on your property, what do you do with the nuts?
