Just as it was striking 4:20 on 4/20, KTVU Fox 2 posted this live copter shot of crowds filling Sharon Meadow and Hippie Hill in Golden Gate Park. The sun is out, the joints have been sparked, and it looks like quite a crowd.

As mentioned earlier, we'll be bringing you our own on-the-ground reporting from the scene via SFist's Joe Kukura just as soon as he finds his way out of the smoke cloud.

Also, allegedly, a parallel pot party that's likely not as large has been forming in Dolores Park.

Some more views from Golden Gate Park:

#420 is definitely one of my favorite events to shoot in San Francisco, and we’re only one day away. Throwing back some selects from last year's festivities for @sfexaminer #weed #sanfrancisco #hippiehill A post shared by Jessica Christian (@jachristian) on Apr 19, 2017 at 10:17am PDT
