The largest of these celebrations in Calgary is the Stampede. A combination state fair/rodeo/racing event/carnival/city holiday/heritage festival, accompanied by concerts, parades, neighborhood block parties, arts exhibits, and company parties. Any entity that is an entity within the city throws a Stampede breakfast - free pancakes for everyone and sometimes bacon or sausage or live music depending on how much money they've thrown at it - at some point during this time. The neighborhood association throws one, the mall throws one, your employer may throw one... our grocery store throws one? You get the idea.
The focus of all of the festivity, though, is on the actual Stampede grounds, where the fair, the rodeo, the headlining concerts (Shania Twain! Reba! Keith Urban!), the chuckwagon races, and the extraordinary variety show+fireworks they use as a closing event every night takes place. Tickets are worth it, but don't eat too much of the food, it's all fried.
We didn't take too many pictures, but Jennifer Percival arrived just in time to hit the town during Stampede before our weeklong vacation in the mountains!
