But if you're willing to drive a bit, you might find yourself by the Durham Museum of Life and Science. And if you wander in and out and into the cold, and then inside again, you may find yourself in a tropical paradise filled with flowers butterflies.
It'll be easy to find on the museum map, since it's called the butterfly house.
Museums are often aimed at kids, but there's no reason adults can't drop in and enjoy the flowers, too. Makes a nice break from winter, at least.
