SAN ANTONIO -

More than 3,000 volunteers create the spectacle of the San Antonio Stock Show and Rodeo, but some of them have roots far deeper in the organization dating back to their teen years.

Winners of the more than $1 million worth of college scholarships often return to the San Antonio Livestock Exhibition grounds to give back.

Doak Stewart, an agriculture teacher at Madison High School, won a $10,000 scholarship when he was a young man on a small farm.

Today, he’s reaching out at a state-of-the-art facility and educating kids about the industry he loves.

"It's kind of neat to leave an impression on them about what agriculture means in their lives daily, from what's on their table, to the clothes on their back, the homes they live in," said Stewart.

He is at the rodeo through the entire two weeks showing his students the grounds and participating in competitions.

Another familiar face on the grounds, Courtney Ringlestein, volunteers and runs her Trailer Park Trinkets store in the Freeman Coliseum.

"It's fun to come back and give. Now my help helps someone else, and they can see the return on their investment," she said.

That theme resonates among all the recipients, including fellow rodeo life-member, Morgan Norris.

"The kids who get these scholarships, it means everything to them to get these scholarships," she said. "With the economy the way it is, and tuition being what it is, we are going to be relying on these kids, particularly these ag kids to feed the world."
