You can see the white truck and trailer which gives a good idea just how big hot air balloons are. Balloon crews use a pickup or SUV with a trailer to haul their balloon and gandola around. Once the balloon is up and away the truck tries to follow the balloon from the ground. Of couse they use cell phones and 2 way radios to help keep track of the balloon. Some balloon owners bring their own chase crew, as the people who follow the balloon are called but some don't and the Balloon Fiesta is always in need of people to work on the chase crews.
