54 doesn't go through KC,MO. You pick it up about 100 miles south of there, it goes through Wichita and on to Liberal, KS. 54 is an ok road but it can have a lot of truck and car traffic that can back up on it at times because of people wanting to run different speeds. The speed limit in most places is 65 mph . TX and NM have a lot of 2 lane and if you don't run atleast 70 mph you will have cars and big trucks on your back door wanting to get around you !! Trust me I run 54 to Tucumcari, to I-40 and on to California and back about 20 times a year. Other than that I like it.
