I have a friend that is extremely anal about everything. He has red oak tress in his yard and can't stand having acorns in his grass. He sent me a text saying cleaning up acorns do you want any? I screwed up and said yes I'll take all you have. Well 3 hrs later he shows up with 12 garbage bags half full of acorns! Literally his truck bed was full. I thought about storing them for bear season or even just throwing them out for the animals this winter. Another friend said that he tried this and they molded pretty quick. Any idea reasonable to preserve them?
