The spot in which you propose is just as important as how you do it. The most obvious choice would be somewhere that you have a history together, such as the place you had your first date. However, there are all kinds of great places to go in the winter that can help capture the magic you are looking for. You could brave the trek to the top of a mountain, or take the more traditional route and hit up the local ice rink. If you want to make it more intimate, you can always pop the question at home in front of the fire all cozied up with a cup of hot chocolate. Whether you take a more personal approach or make an elaborate gesture of love, wherever it is should show them how much you care.
