If you want to see what Christmas Day on Mackinac Island looked like, you'll enjoy visiting the YouTube site of this islander, gmacisleman.
Not only does he have videos from Christmas, but last year as well. It's a great chance to see what the island looks like in the middle of winter!
I suggest preparing a cup of hot chocolate before watching too many of these videos! While they're sure to bring a slight chill to you, it's enough to make me look forward to visiting in February during the Winter Festival.
