Where would I find one?
possibly here,
Geographic Map Shapes for Microsoft Visio (http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=8bb43b9c-6e1f-4e5c-84a6-86c326a0d025)

There's probably one available if you use the shape search feature, but I often have mixed results with Visio's search.
You can also download this: Map of North America (http://www.visguy.com/2006/09/22/map-of-north-america/)
When I do a search for California, Visio retrieves the shape from my Visio 4.1 Technical directory. My guess, then, if it exists, it would be with the Pro version, not the standard. But, Visio Guy's link works very well.
