It's the DRIVING THROUGH it that makes me a nervous wreck. To stay on 70 East, you have to go this way and that, and suddenly move over 1 lane here and 2 lanes there, and don't forget the semis crawling up your ass, and don't hit the slowpoke grannies messing everybody else up, and avoid going through at lunchtime or when there's an event at Arrowhead, etc. etc. Makes me crazy.
However, the traffic gods were with me today. KC was nearly all my own, and I made the 6-hour drive in 4.5. Home safe and sound again, and all is good.
