On a clear day from Muskegon Michigan you can see straight over Lake Michigan to the downtown skyline of Milwaukee Wisconsin about 80 miles away. If we were on a circular globe as we are told there should be 3703 feet of curvature for every 80 miles. The tallest downtown building in Milwaukee is 601 feet so downtown Milwaukee should be 3102 feet below the horizon from Muskegon. But since it is plainly visible this is more proof that we do not live on a round ball shaped planet.
