I'm curious if anyone on this board has traveled this section of the country.  Looking like Cedar City to Pueblo on the WE is becoming a thorn in my side with the onset of Spring.  I'm still hoping I can take the full WE but I need to plan accordingly. 

This route goes south via Rt 18 through Enterprise and on to St George.  Take a look and I would love to hear your opionion.  I do realize services are tight along this route but thats ok cause I will be in full load mode.
