When traveling alone you have to get a little creative with the pictures to prove that you really were there. I'm horrible at taking self portraits.... maybe I should rephrase that... I look horrible in most self-portraits. I always manage to end up looking like I have a whole lot more chin than I really do.
So I take pictures of my feet and shadows. It works.
The top picture and the first of my feet are me in the ocean at Daytona Beach, Florida. The bottom photo is me sitting by the pool at my hotel. I really was there!
