It was supposed to be 144 miles one way. I didn't look at the odometer when we arrived, but I suspect we drove about 170. What gave me the "hops" wasn't encountering a detour as such. It was: 1, encountering a "detour", with no forewarning, that consisted of driving 10 miles to a dead end and doubling all the way back. Then: 2, seeing a sign clearly indicating a re-routing, following the described route through a very slow area, and then finding out that there was never any reason for the re-routing sign. we could have stayed on freeways with a 70 mph limit the whole time.
