We’re down in the wilder spaces of the park, now. The lower side, with its hiking and mountain bike trails, its hidden gardens, its untamed forests. We continue westward, exploring this less cultivated area where there's more space and more animals, too. You’ll see coyotes out here sometimes. Plenty of raccoons in the evening. Foxes, if you’re lucky. We turn off the road, back into the forest. It’s quiet except for the occasional whizzing sound, gentle crank, and quiet chatter. We’re at Golden Gate Park’s casting pools. Reporter Ian Lewis shows us how it's done.
