<p>Our group consists of friends and family members who have been involved in the Houston Livestock Show & Rodeo and the Houston Livestock Show & Rodeo World's Championship Bar-B-Que Contest for many, many years. The Renegades were assembled in 1999, when we decided it was time to start doing things a little differently than the way they had been done in the past. The year 2000 brought not only the new Millennium, but also a renewed outlook on our approach to friendships, team work, and most of all, barbecue. As each year passes, it seems that this event as a whole gets larger. To accommodate for this growth, the Renegades expanded to provide additional space for our guests to enjoy the fun, food and activities.</p>
