Over 9,000 students, teachers and parents visited Aggie Days Wednesday to Friday, March 17-19 in the Round-up Centre at the Calgary Exhibition and Stampede Grounds.  On Saturday and Sunday another 15,000 people from the City and area came to connect with agriculture.    At the AIPA booth, children did irrigation puzzles, saw and felt seeds of irrigated crops, looked at foods produced from those crops and ground wheat into flour, all to the sound of crowing chickens, mooing cows, and bawling sheep and goats.
