Parts of I-80 in PA are scenic and wide open.
Going east out of Seattle, I-90 I think is beautiful for slab.
Definitely I-70 through central Colorado.
Heck, even parts of I-90 through SD can be inspiring for the wide open stretches, make you feel small in this world.
When life throws you a curve,.....lean into it!
