The Calgary Stampede's Aggie Days are back and they've expanded.

Josh Traptow with the Agriculture Education Committee says while it's aimed at people from urban areas to learn about life on the farm and where their food comes from, it's a great rural showcase.

"We have wagon rides on Saturday, we have a number of demonstrations, we're bigger and better, we're also at the agriculture barn as well as the Agrium Western Events Centre, so there's more space," he says. "There's going to be Clock, Stock and Barrel on Saturday in the arena and then there's Extreme Cowboy Up on Sunday, so there's lots of activity for people to see and to take part in."

Clock, Stock and Barrel features stock dogs competing to round up sheep and get them into a pen in the shortest amount of time.

The Extreme Cowboy Challenge highlights the trust between a cowboy and his horse as they make their way through a series of obstacles that test horsemanship, agility and speed.

Farmers and ranchers from all over the Calgary area are providing animals from new born lambs to draft horses.

Students got to take in the first three days of the event while gates are being thrown open to the public on Saturday April 8 and Sunday April 9.

This is the 49th year for Aggie Days and over 40,000 people are expected to take it in.
