Great drive, sooo scenic.... obviously only do this in the summer (May-Sep). Don't rush, expect slow going at times due to bad roads, construction, and lots of traffic. Lots of uphills and downhills. Expensive gas. The Milepost is a definate plus in the planning portion. Take it slow, don't plan for high mileage days. But overall it's worth it!
