Zipping Around the 94110 and the 94105

A graphic reminder that San Francisco is not one coherent city but a collection of several samll, almost self-contained villages is evidenced in a trip from my very low-rise Mission District (94110) to the burgeoning urbania of South of Market centered around the new One Rincon Hill (94105) project. Though the tidiness of that neighborhood is refreshing for a little while, it doesn't take long to discover that it has its own rough edges.
