The Oakland Hills Public Use Microdata Area, or PUMA (a Census Bureau designation that I’ll explain in a moment), in Oakland, California, contains some of the most appealing urban neighborhoods in the US. There are charming residential streets designed by the Olmsted Brothers in Crocker Highlands and Trestle Glen, great restaurants and shops in Lakeshore, Piedmont Avenue, Rockridge and Temescal, houses perched on impossibly steep streets in the hills proper with sweeping views of San Francisco and the bay, and rugged parkland to the north and east.
