I was driving on Colorado State Highway 74 North of Evergreen (don't remember if I was leaving (North) or approaching (South)). Along side the road runs Bear Creek. I was coasting in 3rd gear (4 speed w/overdrive) to keep the car slowed down to 40 mph (and still had to tap the brakes). Obviously, I was going downhill, but the water in the creek was running the opposite direction, uphill. Weird.

We have two in Maryland that I know of; one is called "Gravity Hill" and is somewhere near Baltimore. The other is likely better known; it's called "Spook Hill" and is not far from Harper's Ferry.

There are sections like that on US 50 along the Arkansas River, between the Royal Gorge and Salida, Colorado. Heading west, you are certainly going up. And the river is flowing down behind you, as is obvious from the rafters on it. But there are stretches of road that actually go downhill for a bit, even though the topography strongly gives the illusion that you are still going up. The opposite happens on other stretches- you feel like you are going down, even though you are really going up. It leads to a kind of disconnect between the senses and what you are doing with the accelerator or brake.
