Radiohead, Tom Petty and the Heartbreakers, Wilco, Beck and a whole slew of other artists descended upon San Francisco's Golden Gate Park for the inaugural, eco-loving Outside Lands Music Festival this past weekend. Here's a glance at the numbers: Six stages. 65 performers. 150,000 fans. 600 porta potties. We repeat: 600 porta potties. Taking one's chances with the 1-to-250 dumping ground ratio so as to see Radiohead sing cryptic lullabies while the fog rolls in with the Bay Area chill? There ain't a number for it.
