No need to set the alarm clock. The helicopters and planes start flying over at 5am. We were up quickly and onto the balloon field by 6am. They sent up 9 balloons to figure out the wind flow. We were right by them when they went up.
You can walk all over the field right up to balloons on the ground and being inflated. They are so close together on the ground they are bumping into one another. After the first 9 were away, the group going up at 7am started to inflate in rows of 9 to 10 balloons. Soon the air was full of balloons.
