Balloons fly close to dawn & dusk times as that’s when winds are calmest & there are least thermals. That one balloon was a tether, taking customers for a ride 30ish feet up, then back down. It was tied off on three points to keep it safely [del]on[/del] close to the ground.
Except for the few special shapes who just stood up & stayed on the field to give the crowd a show, all of the balloons flew last night, at the scheduled time.
I did walk around looking for a wee young 'un in a stroller & Mooommm, but you were probably gone by the time I got there.
Of course he will, he gets to have a beer with me! 
Try ballooning for lack of sleep, get in around 11pm & then have the 'larm set for 4-something…multiple days in a row. :eek:
