Magnetic Hill is a tourist attraction just outside of Moncton. Because of a bizarre optical illusion the hill appears to slope up, but actually slopes down. You can set your car in neutral at the 'bottom' of the hill and it rolls to the 'top'! Walking 'up' the hill is a strange experience. Your mind is convinced that you're climbing, but you are in fact descending. This really wreaks havoc with your sense of balance.
