Seventeen:

This brief trip along historic route 66 was incredible. This portion stretched between Topock, AZ and Kingman, AZ, passing through Oatman which was an interesting little town that almost seemed to come out of the old west. The road just winds and goes through amazing scenery. If anyone has to drive that stretch of road at night, take your time, the roads are narrow and twistier than most roads modern drivers are used to. But it is well worth the trip.
