This might be the weekend where nature in Calgary is at it's muddy, slushy, grey-brown, gritty worst. Stick with man-made beauty, or get out of the city.
Depending on what's "just outside" for you, you could do something like Elbow Falls, Sheep River Falls, or the Banff Springs Hotel (you might need a permit to shoot inside though).
Also beware of this protectionist BS if shooting in the National Park.
