Good for you. (on the 47 miles part) Sounds like a great way to spend a Friday. Do you ever ride on trails?
Here in our area of Alabama we have the Chief Ladiga Trail. It starts in Anniston, AL and runs to the Georgia line where it connects with the Silver Comet Trial and that runs to I-285 in Smyrna, GA near Atlanta. The entire trial is about 102 miles from end to end. Lots of it is in the woods and away from towns or cities. A wonderful ride. We use it for short or recovery rides after long rides. We also will ride parts of it to connect to other roads as we ride around.
