I thought this balloon was going to land in the car park behind the building. It must have come close, but started to lift up again a few moments later.
Fun catch- they may have been playing a game. When I went up some of the other balloons that went into the gorge with us went down into the gorge and touched the water in the river. Our pilot decided not to do that but explained it was a game they played at times. It's fun that you caught a shot of them so low though.
