Magnetic Hill is actually Pioneer (Pitt) Road, near Springer, OK. Located just off Interstate 35 at exit 42 (Hwy 53). Head west on highway 53 and turn right (head north) on Pitt Road. South of the highway Pitt Road is labeled Pioneer Road. Drive north until just past the cattle gate on your right. You will be at the bottom of the hill. Check for traffic around you, put the car in neutral or kill the engine, and the car should begin being pulled back up the hill. Kristina clocked the car going in reverse on its own at greater than 5 miles per hour.
Of course we had to do it three times, just for entertainment. Then we turned the car around and tried it in the other direction, just for giggles. Sure enough, it worked that way too. I noticed the heard of cattle eating in the fields on either side of this stretch of road looked at us like they were quite used to these types of antics, which was also very entertaining.
Evidently there is all kinds of conjecture about what makes Magnetic Hill "magnetic" from aliens, to ghosts, to curses, to an optical illusion (being the well grounded sort, I vote optical illusion), however it was sure an odd feeling. Anyway, if you make it to southern Oklahoma and are looking for something diverting, check out Magnetic Hill. We sure had a fun time.
