Hot Air Balloons in Texas Park

This afternoon while we were in the backyard, we heard the familiar sound of a hot air balloon burner (we see them at least once a year). We ran to the park and spotted one coming in for a landing. Others in the neighborhood heard the noise as well so there was quite a crowd. They came in for a gentle landing after scraping the tops of the trees (they do this to slow themselves down right before landing) and said they were racing another balloon. Sure enough, we could spot another balloon on the horizon.
