Hello! Fairly new to roadtripping and looking for some advise on a trip from Houston Texas up to Devil's Tower, Wyoming. Looking for alt routes not taking main Interstates straight up through OK, KS and NE. I'm looking for routes to take us on a more north western route through the Texas pan handle (Amarillo) and up through Colorado. I've been trying to map it but the only problem is I'm not familiar with the smaller highways and I don't want to get stuck on a one lane highway for hundreds of miles (I did this for a brief 100 miles on 285 South and found insanity). Has anyone taken this route and is familiar with the best highways to take?
