The Chandelier Tree
Totally forgot about this one. Right at the far northern end of CA-1, just outside the little town of Leggett, is a gigantic redwood tree with a hole carved right through it.
It’s called the Chandelier Tree, and you can drive through it for a fiver (assuming you’re not driving a whacking great pickup truck - even my Mustang only made it through by a couple of inches).
I was tempted to call Hertz and tell them I drove the car into a tree.
