When it's beautiful in Chicago...
you go out and take advantage of it. Because Chicago really is beautiful and quite enjoyable when it's not frigidly cold with grey skies that have overspent their welcome. We went to the Lincoln Park Zoo and also enjoyed the formal gardens just outside the west side of the zoo. Did you know that this is one of the oldest parks in the city? That's OK, I didn't, either, until I read the sign.
