Niagara Falls

I'd also say that February is not a great month to visit Niagara Falls unless it's a stop on the way to ski country. The OP has a rig that can handle the weather, so perhaps they have other plans suitable for the weather. And...if there is some fresh snow and ice, the view of the falls can be tremendous, especially you are lucky enough to have some sunny, blue sky days. There are some great indoor attractions if you can cross the border including the Butterfly Conservatory and the Aviary.
