Demonstrators filled Main Beach in Laguna Beach on Saturday for a rally opposing President Trump’s proposal to open California’s coastline to offshore drilling for the first time since 1984.

The protest, which included actor Ted Danson, featured participants holding hands as they formed a line across the sand, was organized by a coalition including activist groups Indivisible OC 48, Oceana, the Surfrider Foundation and Orange County Coastkeeper.

Similar demonstrations took place in Santa Monica and San Diego.
