70 because Colorado is awesome.

IIRC, SLC to Colorado on 80 takes you over Rabbit Ears Pass...beautiful.

80 doesn't go through Colorado at all.

been twenty years, but rode a bike from SLC to Omaha..and now that I think about it..you're correct....I think I took 76 out of Denver up to 80 then to east to the big O.

That's true. At least you can haul ass

70 by eleventy billion times

I just drove both 2 weeks ago. 70 out 80 back. 80s too far out of the way. 70 is very scenic and the mountains are nice. Don't do Denver at rush hour other than that great scenic drive. And faster.

Both routes are equally boring IMO. I'd choose the northern route since it's summer. Or maybe look at the weather on the morning you leave Salt Lake City to see which route looks more favorable in that respect.

Coming through NE you may actually see a tree or an actual town though.

It's weird to hear it called 'THE' 70 OR 'THE' 80. I lived in San Diego for a year and never got used to that.

I would say I-80 just so you can haul ass and get through it faster, but 70 is the more direct route to KC, and I believe Kansas upped the speed limit to 75 like Nebraska anyway.

So I vote charter a lear jet and do tequila shots all the way to KC.

You Californians, calling roads "the". I don't go take "the" 35 to the Oak Park Mall. I don't take "the" 70 to Kaufman or Arrowhead :D

That's because there are so many State freeways mixed with Interstate Freeways.

It would be awkward to say "Take the California 101 to Interstate 110 S to Interstate 105 West to Interstate 405 S to Redondo Boulevard".

It's much easier to say "Take the 101 to the 110 to the 105 to the 405 and get off on Redondo".

Driving across southern wyoming is tremendously worse than Kansas. At least Kansas is green.

Yeah, much of Wyoming is similar to the setting of The Road Warrior.
