It is a pretty good route but there is no sag support for that portion of the ride. It continues up Midland to the Midland Store and turns left over to 231. It goes through Fosterville, Bell Buckle, comes back through Deason, and goes over to Three Corners Market. From there it comes back into to Panther Creek, Versailles, and Rockvale.
Nancy Mc and I are thinking of doing it as well (I haven't told her yet but I guess she will find out). I don't remember any big dogs on this route at all. Although there is not any sag support, there are SEVERAL stores that you will pass should you need food or drink.
Are you and Nancy riding the tandem on the 3-State 3-Mountain ride next month? I was hoping you'd have a different stoker so that some of us might have a chance of keeping up with y'all! (We know who's the real power on that team!)
