80 through Sacramento will be busy during commute hours. Same thing applies through Reno. 80 through Nevada, while boring, is an easy ride. 80 through SLC is a nightmare during commute time. As you leave SLC, there is a good pull up the canyon to the park city turnoff. Then it's an easy ride past Wanship, Coalville, and on to Evanston. I don't recall anything that was exciting through Wyoming. Different story in late fall and winter, where that stretch can be real treacherous..
