This is a fun idea for sharing photos that I use on my own site. Basically, you post a photo about more or less anything; and people follow up by posting a similar photo, establishing a sort of theme, or association. If the thread "goes cold" and responses drop off, or just for a change of pace - someone can post a related, but totally new photo to change direction. For example, to start this thread off I'm going to post a photo. Appropriate responses would be something else that's red, another phone booth or pictures from the England or Canada pavilions. Ready? Let's go!
