One other thought. The Trail ridge road is the highest continous paved road in the USA, but 60 miles west of Denver is the Highest paved road in the USA. Formerly known as Mt Evans scenic byway, it's now called The Mount Blue Sky scenic byway which rises up over 14000ft. You'll have the bragging rights over the lowest point in the USA at Badwater, so you could add the highest (paved) point!
