on comparing anthropology to sociology

I think that the issue of redefining what constitutes the "field" in anthropology when considering "home" and "away" leads us to compare methods and subject matter between the two disciplines of anthropology and sociology. We seem to agree on the fact that the sociological "field" constitutes our own culture at "home" and that subsequently the "field" in anthropology would be in cultures that are not our own. So now, when considering anthropological fieldwork at "home", we seem to have increasingly blurred lines between the two disciplines. So what do we do now? At this point, I am unclear as to how to differentiate between the two when considering fieldwork at "home", however, later in these discussions, I will certainly have a more clear definition of fieldwork and the general conception of the discipline of anthropology.
