Firefighter opens a hydrant, San Francisco.
I actually got sprayed getting this shot. It was an accident on his part as he saw me getting into position and didn’t realize how fast the water was going to fly out at first. He was apologizing profusely but after a moment we were both just laughing very hard, as my jeans were covered in water and muck. (Turns out the first jet of water out of those things is bloody filthy, people.)
