I have an Oak tree and have been collecting acorns from it since its maturity several years ago. I had planned on offering them to my vegan and gluten-intolerant friends but I don't think they're that keen on trying to make the flour. So my stash grows.

On my wishlist this year is planting some hazelnut bushes, I've always loved them. yum.

Sort of off-topic, but as a show researcher for @pennsif's Alternative Lifestyle radio show I wanted to ask whether you would be interested in being a guest on it? It would be wonderful to let listeners know more about the foraging you do, and that they could do too.
You could reply here, or find me in Discord (same name). My fingers are crossed. :)
