If you start from Holly, CO on the eastern border and measure to San Francisco, CA and Ocean City, MD he's only off by about 300 miles--300 miles if you take US 50 in either direction, and interestingly ~300 miles if you let Google Maps take you via the boring Interstate routes (interstates tend to be straighter than the old highways, making up for the more meandering north-south jogs of I-70, I-80, etc, as compared to US 50). Of course, it's more like a 500 mile difference starting from Colorado Springs, or 600 mile difference from Denver.
