light observation

Although this experiment may sound a little hazardous, or probably very unsafe, I decided to experiment with my car's headlights while driving. As I was driving home from a friend's house tonight through some low fog to get my neighborhood, I suddenly remembered our discussion about how fog or water vapor can intensify a beam. The fog seemed very thick because my headlights were shining directly on the areas covered with fog, so I turned them off. It wasn't the best idea while driving, but I was surprised to observe the fog itself really wasn't visible. I also noticed the moonlight shining on low-lying fog in a nearby field. I thought, "Would the fog appear as thick and defined if the moonlight weren't reflecting off of it?" I got home and decided to use a flashlight outside to see if I could see a beam. To my surprise, I couldn't. At a certain angle, a could see how the light was traveling a very short distance from head of the flashlight but there was not even a definitive "fuzzy path of light". I think this may have been a result of too much surrounding light (a streetlamp, full moon, etc.). I have a feeling that if I were in the the middle of the foggy field I would be able to see the beam because there would be less surrounding light and the fog could intensify the beam. However, this is only a theory, as I was unable to do this.
