Highway guidance needed

[awesome_bird]

Hi everyone. We're in Moab Utah headed for the Seattle area. Getting
to I-15 we can go west on I-70 from Green River to Salina - or we can
take us-191 north from Green River, through Price and get to I-15 at
Spanish Fork.

The Western Mountain Directory shows three steep grade areas on I-70
from Green River to Salina. The directory does not show any difficult
stretches of US-191.

Does anyone have experience with either of these routes?
Have you taken your bird on this stretch of I-70?
Have you driven this stretch of US-191?

We look forward to hearing your stories and planning our trip
accordingly.
