							<li>The most important goal as a student and rodeo athlete is to be successful in completing a post secondary degree at Idaho State University.</li>
							<li>As a member of the NIRA, team members compete against other rodeo athletes from Colleges and Universities throughout Idaho and Utah. We participate in 10 rodeos each year to qualify for a chance to travel to Casper, WY in June for the College National Finals Rodeo. Practices are conducted Tuesdays and Thursdays from 4 p.m. - 8 p.m. during the months of September - October and February - March. Practices are held at the Bannock County Fairgrounds. When the weather is nice we rodeo outside and during the spring, practice is in the new covered arena. Team meetings are held every Thursday of practice and twice each month when practices are not taking place.</li>
							<li>Membership varies from year to year with the average being 10-15 members. Everyone can participate in practice and competitions.Point teams consist of 6 men and 4 women. These teams are chosen on the number of points accumulated throughout the year.</li>
