When I was in Whistler last week I did not bring a tripod, so when I saw the night scene from my hotel window I had to improvise. A side table, and a couple of books were pressed into service as a makeshift tripod, and luckily I did have my cable release with me, so I was able to complete the 45 second exposure with little or no camera shake. Shooting through the window did make for some weird reflections though.
