It does this by specifying how actors in two California urban areas, over approximately 100 years, responded differently to the same exogenous forces. Each place is examined to determine how unlike elements conjoin to produce a particular "character" at any given moment and how this character travels through time to constitute a local "tradition. " Borrowing from advances in analyses of structure and agency, this study displays character and tradition as accomplished interaction and helps make an elusive process empirically evident and accessible for study.(EOGRAPHIC units-like cities and \...~regions, but also like other types of social entities, such as corporations, academic departments, or whole societiesseem to exhibit overarching qualities that, however difficult to measure, make them durably distinct. Using "place difference" as our empirical focus, we strive here to make what might otherwise seem ineffable distinctions amenable to systematic empirical investigation.In their personal lives, social scientists are as likely as anyone to be sensitive to holistic qualities that make Chicago the "city of the broad shoulders" rather than, like Paris, the "city of light." More prosaically, they presume that overarching attributes distinguish, say, Denver from Toledo as a place to live or work. Despite the fact that, in the words of geographer Entrikin (1991:13), "these differences are not imaginary, but rather are actual features of the world," social scientists, perhaps wary of facile descriptions of "national character" (Inkeles 1996) or the "invention" (Hobsbawn 1983) of hegemonic traditions, do not much take them up.1 They more typically fall back on the apparent "solidity" of quantitative indictors-thus economic urban categories like "manufacturing center," "port town," "affluent suburb," or a position on the "center-periphery continuum" are common. Such material variables do matter in making up place differences, but they cannot, any
