HATDS' 30th birthday celebration was held online on September 17, 2020, during the COVID-19 pandemic. Erica McCready spearheaded the project and acted as MC. Kendall Rogers and Katie Geringer played several tunes, John Bloom called two English dances, Kendall called a contra, and Keith Holmes presented a slideshow of a few highlights of 30+ years of contra and ECD in Houston.
Here is that slideshow with a few additional slides and photos. It's about 8½ minutes long.
