Oneta has participated on many of the Wagon Trains organized and led by Morris Carter. In 1990 Oneta was in charge of all trail riders for the Blue Circle, during the Wyoming Centennial Wagon Train Casper to Cody. On the 1993 Oregon Trail Wagon Train, if Morris Carter was busy then you asked Oneta (then only 19) what needed to be done. She kept everyone organized and she had a great way of handling people. In 1999, Oneta served as the Wagon Train Captain of "The Official California Trail Gold Rush Wagon Train of the 49'rs" directing and leading the way each day. This historic event also marked the first Wagon Train trip of the youngest member of the Carter clan, Oneta's 2 year old son, Caimen Houston.

When her sisters were old enough to start driving teams, Oneta along with her Grandmother, taught them a lot about driving and horses. Of her sister, Airian Carter says, "When we were at Topeka, Kansas on the Historic Oregon Trail Wagon Train in 1993, Oneta was driving Hoot and Holler, her first team that Dad had given her. I was sitting beside her and I don't think that I'll ever forget that moment when she was giving me pointers on driving like the older sister she is, one of the best teamsters I will ever have the pleasure of knowing and being taught by. She was driving that team like they were butter and anyone who knew Hoot and Holler know that with their dispositions they are a far cry from butter. I will always regard her as an excellent teamster."

Always interested in the history of our country, Oneta Carter Houston has become a great representative for women. On the 1993 Oregon Trail Wagon Train, when Oneta and her sisters would drive their teams into small communities, those "old-timers" with the age and experience to know would come right up to them and swap teamster stories and advice." You could tell by the sparkle in their eyes that they appreciated what my sister and I were doing and they were plumb tickled that young people were interested in the history of our country. A lot of old timers wouln't say a word but just come up and shake our hands and that was enough," relates Airian Carter.

The Carter women traveled on the Casper, Wyoming 100th Anniversary Wagon Train in 1989. They also went the entire distance of the Wyoming Centennial Wagon Train in 1990. Ivy, Oneta, Airian and Katrena assisted with the Official Historic Oregon Wagon Train in 1993. As Wagon Masters, the Carter women play a vital role in the overall coordination of the wagon train. The Carter sisters have been involved in the wagon train business, including presentations of history for large groups, harnessing and driving teams, setting campsites, caring for the guests, ivestock, telling the history of the area and its heritage. Since early childhood, they were part of a ranching family, learning aspects of the business and being taught to drive a team by Edna R. Carter, their grandmother.
