I would describe the road between Fayetteville and Huntsville as similar to riding US41 from Murfreesboro to Nashville. Lots of traffic, crap all over the side of the road, and lots of traffic lights (especially as you approach Huntsville). An alternative would US110. It will get you to the state line but puts you back on US231 for the worst part IMO.
Thanks guys. Sounds like its not worth it. Think I'm going to do the MRT from Memphis to Reelfoot Lake instead. I've ridden that one a couple of times and know it better.
Congratulations on your Year Round Award!! For those that do not know that's an award given by Ultra Marathon Cycling for those that complete at least 1 century in each of the 12 months. Which in our part of the country can be pretty tough in some winter months.
