For the most part, the Plano Balloon Festival was a bit of a bust this year. I don't think the balloons ever got to launch because of either wind or storm clouds, depending on the day.
This year we decided to go on a Saturday night to see the evening launch and the glow. We waited and waited and waited for the launch before it was finally announced that it would be cancelled. We waited some more for the glow, not sure if it was going to happen either. For a long time there were no balloons blown up, or even spread out, on the field.
Finally the pilots put them up and we had a great view. The festival announcer would say "3-2-1 GLOW!" and all the pilots would light their balloons. It's very pretty and makes a cool whoosh sound when they all go at the same time. We were glad we stuck it out, it was definitely worth it!
