I know exactly what you mean Sue, the balloon glow is one of the coolest things to watch. The people at these gatherings are a lot like the people on this forum, they look after each other, and enjoy involving the interested, especially the kids. It's one of the few sports that thrives on spectator participation.
Wrenchtraveller, if you ever get the opportunity to watch, or participate, don't pass it up. You'll love it.
BTW Sue, great picture.
