This is just my opinion, but showing should be a progression. If you have never shown a calf before, county fairs and local shows are the best place to start taking your calves. While you are showing your calves at these smaller shows, I completely encourage all showman to go visit some of the bigger show like regional or state fair shows at least once without your calf before you go with one. Maybe go with a friend and help them with their calf at one of these bigger shows. That way you can really see what these bigger shows are like. From there I would continue to visit even bigger show before committing to take a calf to one, i.e. State Fair, Cattleman's Classic, Iowa Beef Expo, then moving up to the big ones like the Royal, NAILE, Denver, Ft. Worth, Houston, etc.
