The knee is the largest joint in the human body and is considered the most complicated one. It is formed by the lower part of the femur, the tibial plateau and the knee cap.
Weather. Calgary's weather is quite unusual compared to the weather in the rest of Canada. Where Eastern Canada and B.C. are quite humid, with ample rain and snow, Calgary is very dry most of the time, with an average annual precipitation of 41 cm (16 inches). While many Canadian homes have de-humidifiers, most Calgary homes have humidifiers.
I think September/October is a great time to come. It has been unseasonally hot in Calgary this summer so who knows what the fall might bring. Usually, the days are quite pleasant with cool and crisp evenings. You can check out Calgary weather on www.weathernetwork.ca.
