a shodeo is kind of like a rodeo with 4 wheelers....it normally consists of 3 events..barrels, flag races, and pole races....last year at oswego they actually did some drags as well....and with each event you compete in and place in you get a certain amount of points..they also divide the classes up between age, engine type, and the sex of the rider----i think thats it....lol..hope that helps
