Another thing to do during wintry days is to visit an art or science museum, or a combination of the two, like The Leonardo in downtown Salt Lake City:
Oh my goodness! This museum was toddler-friendly and a fascinating mix of science and art. I would totally go back again, but I have to say that my favorite museum is still the Springville Museum of Art. It will always have a tender place in my heart.
Do you have a favorite museum to visit? If so, what is it and why?
