20.8 miles. I actually biked somewhere new! Turned right on Rucker instead of the usual left. Up to Charlotte, and over to what was basically downtown Crabapple. All of this is about as rural as you can get before you really head out to the North Fulton boonies. Then east on Mayfield to where it meets up with the library, thru downtown Alpharetta and then to the GW as per usual. It added on a bout 5 miles to the normal route. I would have tried a few of the side roads, just to see where they go, but I left later than I wanted to this afternoon. I have my North Fulton MAp now and will look at exploring up around that area more.
