Lake Champlain is the large body of water forming much of the border between New York and Vermont, and extending into Quebec. To a Montrealer, it's a major feature of the neighbourhood.
The islands and peninsula in the northernmost part of the lake are especially fascinating, since despite being in the USA they are as much a part of the culture of rural Quebec as of New England or New York.
Does Lake Champlain freeze up in winter? Well, sometimes.
According to the graphic from this site, Lake Champlain failed to freeze over six times during the thirteen decades 1816-1945. In the decade 1996 - 2005 it also failed to freeze six times. That's an impressive trend.
The only thing we can be sure of about the future is that it will be absolutely fantastic. So if what I say now seems to you to be very reasonable, then I have failed completely. Only if what I tell you appears absolutely unbelievable, have we any chance of visualizing the future as it really will happen.
