Just to clarify your comment.Not a valid test, south is downhill, north is uphill.

I live Northeastern Ontario at 1000 ft above sea level, central Florida is at approximately 100 ft, so 900 ft difference in 2,350 miles, that is a such a small incline, 2 1/2 feet per mile, so it is very minimal.
I attached a topographic map so can see for yourself, there is no drastic elevation difference.
