So, after avoiding having to go to Nashville for 4+ years my luck ran out. On the other hand, 4 days of riding (I know 600 miles is within the range of some for a days ride, but not me, so two days each way) should make it worthwhile. Here's the route I am thinking about:

Leaving the 22nd, working in the Nashville office Tuesday through FRiday morning. Planning on returning via St. Louis, probably stay there Friday night, back home Saturday.

As of now the weather looks great for the outbound leg, with a little luck it should be a nice, relaxing ride.
