I ran in Garberville, CA and it isn’t in the list of cities.

Unfortunately, it only exists as a node (an individual coordinate as opposed to a set of coordinates that make up the border) - Node: Garberville (4418246597) | OpenStreetMap & in order to be brought into CityStrides it needs to exist as a way/relation (where there’s a city border).
I’ve added it to the Missing/Broken Cities Tracker in case someone who’s good at OSM editing can help out. Honestly, this isn’t very common.
