tree id help - Hickory

We have this tree in front of our front door and it looks like walnuts but I have never seen one with the line on it like this has im sure it a nut but not sure what kind
here is a pic. the second pic is of some berries that are all over our place and not sure what kind they remind me of a mulberry but its a bush not a tree.

Looks like a Hickory nut. Green is inedible. You have to get mature ones. The shell will turn black and open along those lines. Inside will be a light brown nut. You will need a hammer to open them or something similar. Taste great.
As for the second I cant tell its not close enough. Maybe blackberries?

thank you ill see if I can get a closer pic

I should have asked does that nut tree have tear drop shaped leaves Sir? if so its a hickory.

lol I was in the army. im not a sir I do work it sure does

Looks like a hickory to me too.

The berries could be blackberries or raspberries. When you pick a ripe one, raspberries are hollow (cupped) and blackberries are solid. But it does look like a blackberry, good eating either way.
