I have found good and empty interstates and US/State highways in my 50 plus years of traveling. I have also found crouded and lousy interstate and US/State roads in the same time period. We are headed to the Black Hills in Aug. and will be using the interstates all the way this time as is our usual way. We have also used US-50 and US 385 for the same trip. Either is fine with us. For us it is about the destination not how we get there. Locally there is more semi traffic on US-50(a two lane road with no shoulders) than on some interstates out west. Everyone has their own preferences as to what roads they like to travel on. Just pick one in the direction you want to go and enjoy the trip.
