Interstates safer than "Blue Highways?"TRIP UPDATE

We travel the secondary roads as much as possible. We hate competing with the semis and idiots on the interstate. No matter what speed you choose to drive you always feel like you are being pushed to go faster. It is not relaxing. Being retired means slowing down. Half the fun of a trip is taking your time and being able to stop when you see something you want to check out further. What is the hurry?
