It really depends where you go. If you are willing to drive out further out of Calgary (East or west-boung), you might find some crudier barns that work out well for you. Most facilities around Spruce Meadows have the training program set up which is 1,000-1,200/monthly.
It depends what you want to do. The few select barns that still allow "regular" boarders to stay there are switching over to the training programs. Such is the expense when you are at close proximity to Spruce Meadows
