A few years ago, Mildura hosted the World Hot Air Balloon Championships. I headed up there for a few days to enjoy the event. Travelling with the competitors was great as I got to see how quickly they measured the weather conditions and set up their balloons. About 80 balloons were raised at about the same time, many of them side-by-side like this, in a rush to take advantage of the best wind conditions. Not only were they pushing against each other on the ground, but the balloons would also bump each other in the air, it was really an amazing sight.
