Central MO. here. There's a few Walnuts, the squirrels started working hickories around the middle of July (about a month early). My side yard is covered with pin oak acorns but the squirrels are not eating them and walking through them sounds like stepping on potato chips... I don't think that there's anything in them.
Pig nut hickories are dropping a lot of nuts and they are working them which they normally wait until January or so.
On the other hand the persimmon trees are loaded. As far as white and red oak acorns I have not looked.
