Bike ride to the Jack Daniels distillery and back! 75 mi each way.

I'm going to be there for sure because my cousin lives in Franklin, TN. We can all crash in her basement/yard when we aren't en route. If there is enough interest I'll put together a team. Maybe we can make Donkey jerseys for the occasion.
Let me know if you have questions.
