Pretty much the same deal as the 16, only it enters the UCSC campus from the west oppose from the east. I’ve never really understood why there were two buses for essentially the same route, but I’ve stopped asking questions at this point. Unlike the 16, it runs less often, about twice an hour and stops around 7. But no one really misses it since the 16 is still running after that, and if I hadn’t already mentioned, the two are basically the same route.
