There was a HUGE oak tree at my grandma's house. I mean it was MASSIVE covering like the whole yard and was like 5 feet in diameter.
I grew up playing under it climbing limbs and swinging on a tire swing and a funner branch-seat swing which was lighter so it would go higher. Heres kinda how it looked:
Anyways, in a hurricane a few years ago a large branch snapped off and it got infected and had to be chopped down :(
