We have run through there twice with the BABE rally. We will be back this year too. There are some really fun roads in the area. Your experience will vary depending on which groups decided to show up that day. The first year there were a ton of Harleys and they slowed us down in our conversion van. Last year there was far less traffic.

You have to watch out though since it is a US highway, and there are trucks, boats, and RV's that take the road. I have seen many boats on trailers and even a couple of class A motorhomes on there. The longer vehicles take up a lot of space and many curves are blind.
