visual medium

While thinking about what visual mediums are out of my reach, the billboard example from class seems to be an example that is far from possible for me. One of the main reasons why is because it is too expensive for me and I am broke, while having a billboard for 3-4 weeks can cost between $3000 and $23,000 depending on where you live. For the cost of how to create and display a billboard, there are also many reasons why billboards are not the most effective form of advertisement and spending my money on it would not be the most worthwhile. Some of the main problems come with the fact that most billboards are next to roads and highways. Because of this, billboards usually have 3 seconds to get the message across, and a lot of times the message can't be read because the driver is looking at the road and not at billboards. Also, because people drive past it, people often forget about it by the time they reach their destination and cannot look up more information about it while they are in the car. On the other hand, I feel like using a billboard would be effective to enhance my rhetoric project. I have a topic where simply showing images of simple comparisons of what school lunches are like in America and how they should be like in France helps to get the message across in little detail, and if I put a website or video link at the bottom to find out more information it would be very helpful. The images would help draw people in because there is such a large difference  between the two. Some sort of slogan I would include would be like "Eat American or Eat Healthy?
