Having bird feeders is great, and it's a great way to bring some ecological diversity to the backyard! And, of course, they do make great photography subjects... aside from serving as superb Kitty TV!

We actually leave our hummingbird feeders up all year now, and we have a few stalwart hummingbirds who stay with us all winter long. I imagine the climate in Salt Lake is a little bit icier in the winter than here in western Washington but we do get our share of frost and snow. During the coldest times, we have a heat lamp rigged next to the hummingbird feeder, which keeps the nectar at least 50° or above.
