How? I just figured out a "quick" route from my house to work that has half the climbing distance as my "fun" route, and is also 1 mile shorter. The grade is lower and only 1 hill as opposed to multiple hills.

What do people want? A personal surveyor to go out and shoot their route for free?

[FWIW - I work in CAD/Mapping/GIS for the local government and the data is spot on for what we use. Google interpolates, it does not extrapolate. Extrapolate = guessing, Interpolate = educated guessing]
