I would recommend coming at night and doing the "Gravity Hill Experience" described below.
I have been coming to Gravity Hill since I was in High School. There are great views to be had here, and this is an excellent place for you to bring your partner and "Park".
What is the mystery though?
Have you ever coasted up a hill in your car? No? Fantastic! This will be a surreal experience for you!
But what is this about a legend?
Some say it is an optical illusion, while others choose to believe the ghost story... As the story goes... There was a school bus full of children driving down gravity hill and when the bus hit the dip (where the gravity hill phenomena occurs) the bus driver lost control and drove over the cliff, killing everyone inside. Now when people go up to gravity hill and experience their car being pulled uphill, it is rumored that it is the children from the bus pushing your car away from the crash site.
The "Gravity Hill Experience":
The experience is best at night with your headlights off. Go past the posted coords and find a safe place to make a U-turn. When you get back to the posted coords you will find yourself at the bottom of a hill. Put your car in neutral and coast up the hill.
This is a popular area for Teens and Young Adults to hang out both day and night. You may need to wait them out or be very stealthy. I have rated the cache higher in difficulty to account for this.
