Whatever route you take, be extra careful going through Montrose. They treat speeding tickets as a source of revenue. This is a notorious speedtrap.
State patrol hangs out all the way from Montrose ... just saw one a few miles north of placerville having pulled someone over.
My favorite stop on I-70 is a health food store called Alpine Market & Deli. Great vegetarian, vegan, and gluten free deli options. Take the western frisco exit and it'll be on your left in 1/4 mile.
