Flew into Copenhagen when my sister and I went to Sweden to find out about our ancestors. Found graves of my great grandparents and my grandfathers only sister who stayed in Sweden. Never could find out about our fathers side. Didn't see much of Copenhagen since that is not why we went over there.
I was really impressed by how colorful the buildings are in Copenhagen - it was also probably the coldest place I've ever been in - even though it was only at freezing (0 Celsius/32 Fahrenheit), it seemed bitterly cold - I was wearing thermal underwear, wool slacks, 2 pairs of socks, a sweater, gloves, and a knee-length wool coat, plus a scarf and hat, the air was biting cold.
