I help out at the "big show" too. I usually volunteer a few days at the Agrium Ag-tivity in the City area between the Agriculture Building and the Grandstand.
The area can be best described as an agricultural "edu-tainment" area. We strive to entertain visitors while showing them a little bit about where Albertans get their food. Almost all Ag-Tivity people are volunteers from smaller communities around Calgary. We have fun milking cows, shearing sheep, herding ducks, making rope, saddling horses, milling grain, and a host of other agriculture related activities.
If you're at Stampede Park, why not drop around and say "Hi".
