crowd of people gathered around several propane gas tanks

crowd of people gathered around several propane gas tanks. The gas tanks are various colors including green, blue, purple, and red. Most of the people are facing toward an unseen object in the distance and appear to be waiting. Some are holding cell phones. One man in a yellow shirt with “ABBA ABU” printed on the back has his hands on his hips, looking on. There is a sign in the background that says “NO SMOKING”. The setting appears to be an outdoor paved area.
