We are from England and are going to Ely, Minnesota for a few days in January dog mushing but want to go somewhere else first, partly to get used to the time difference, but mainly to take advantage of the long journey. We haven't been to the USA before except for a very wonderful week in New York. We considered Chicago and Montreal (in Canada, I know!) but we thought it might be too cold to enjoy sight seeing. We don't ski or skate. We also looked at Cuba, but there are no flights to/from the USA. Any suggestions what we could do at this time of year?
