In the Jargon File / New Hackers Dictionary, the road El Camino Real is amusingly referred to as El Camino Bignum. At first this may seem like an exaggeration, but once you get lost on it, you realize how long El Camino Real really is.

The street numbers on El Camino Real reset every ten blocks or so as you move from city to city. When visiting the area and discovering the road for the first time, this can be quite problematic. While trying to find a hotel at a certain street address, I kept going south while getting more and more confused until I found myself in Sunnyvale. Unfortunately, the hotel and the Model United Nations conference I was attending were near Stanford, up in Palo Alto. Oops.
