In January, San Francisco celebrated 30 years of its famous sea lions basking on K-Dock on Pier 39, but after the party, everyone disappeared.

Pier 39 has been closed since mid-March due to the city's coronavirus shutdown order. While distant "arfs" can still be heard from the boarded-up walkway along Fisherman's Wharf, the 400 sea lions are no longer visible to the public. We decided to take a drone out over the pier to see how they're doing.
