Hundreds of people gathered on July 14 in Cambridge Common, located near Harvard Square, for the Banditos Misteriosos Water Gun Battle.
This year's theme, "See Something, Spray Something," is based on the MBTA. All participants were dressed up in T-related costumes.
The Banditos Misteriosos holds frequent events across the area, like the 2012 Pillow Fight in the North End Park. Organizers said they try to hold events that are open to everyone in the public and organized for the fun of participants involved.
