There are many wonderful events around the country during this season (when the weather chooses to be kind). We learned several years ago when we went to Albuquerque that a hot air balloon festival is a great spectacle of color, so were delighted to find one closer to home in Plano, TX this year (with warmer early morning temperatures than our very chilly New Mexico experience.)
Getting to the launch field before dawn, when there is mist on the ground and the balloons are just starting to be inflated, is worth it. These balloons are huge, of course, and watching a flat blob of color grow to become a wonderful creature, or an iridescent pattern of light, is a delight. And then, of course, as the sun rises, they lift off into the sky nearly soundlessly (except for the cheering spectators.) It’s a fun morning.

Wonderful!! Rode a couple in Albuquerque a zillion years ago.
