They encouraged Houston residents to dress in Western wear. The day had the dual purpose of celebrating Texas culture and advertising the show. In 1957, Myrtis Dightman organized the first trail ride for African-Americans. He led 10 other cowboys in a ride from Prairie View, Texas to Houston. Because of their color, they were not welcomed in Memorial Park, where trail riders typically spent the night. Armed guards were there to ensure that the men could enter safely. That same year, the show granted its first major scholarship. Ben Dickerson was given $2,000 ($16,000 in 2016) towards his education. This was the first step a major shift in the show's purpose. Over the next few decades, the show placed an increasing emphasis on education and scholarships.
