John Lovell is holding onto a rope, easing himself down a steep drop-off.
“I’ve already fallen off it once!” Lovell yells, looking down a steep canyon called Avalon in Daly City. It’s a gusty place, with planes constantly overhead. Lovell is here to check on his harvest.
“People ask me what I do, and I say, ‘[I] harvest fog,’ they say, ‘Harvest frogs?’” Lovell laughs.
