It is once again time for the Twitter event #FriFotos when people around the world share their favorite photos. This week the theme is THANKFUL, in recognition of the fact that we in the United States just celebrated Thanksgiving and with it the start of the holiday season. I am thankful for a lot of things, but I am especially thankful for the unique adventures I have been fortunate enough to experience this year. Here are some photos from my 2011 travels.
