A public way of promoting the meaning of "Public Health"

For me, Public Health is "PUBLIC". I chose this location because a bus is a public transportation that many people use everyday. This is the 811 line that goes from Provo to Sandy. Many people use this bus everyday which means that there is a chance that more than one person will see this add. Moreover, I chose this line because people from different backgrounds and different places will see it and hopefully they become interested in public health.
