Cities are what you make of them, and urban planning nonprofit SPUR invites you to reimagine San Francisco (and your own hometown) with gallery shows that explore urban living, from smells to stories told on street corners. Exhibitions are free, thought-provoking and visually appealing, featuring local and international artists. For the ultimate SF treasure hunt, check out SPUR's interactive map to hidden downtown 'privately owned public spaces' (POPOs), which are actually open to the public (www.spur.org/blog/2012-08-27/get-spurs-guide-public-spaces-your-smart-phone).
