Backyard Water Sports
A good size pod with an algae bloom in it. There's an airboat in the middle. The driver is spraying the surface of the water with a pressure washer rig. There's a white pickup truck backed up to the pond in the upper left corner of the image.
Lots of local ponds, including the on by my house, have had algae blooms recently. This man and his boat have been going around killing them.
Looks like a fun gig.
