My 2 cents: My 1st 30 were in KS & I vote for Pauls' version & I've done them all many times. I'd divert around Denver to the N for all the right reasons unless I wanted to get to the S of Denver which isn't my favorite place in CO which is a favorite place otherwise.
Having been in Daniel Boone country for 38 yrs I find KS a refreshing place with clean air ,beautiful vistas & lots of space. Don't listen too those that talk about how boring it is. If you want boring try the TX panhandle sideways.
