conduct a physical security evaluation of an area in which you live(San Diego, CA.)or routinely frequent. The goal is to look at the places and buildings you see every day and examine them with an intense focus on physical security.
As long as you obtain permission, public buildings would be an excellent choice to perform your inspection (public library, parking garage, or courthouse). Do you know a friend that has a business? Ask them if you can perform a physical security analysis for them. A local night club or favorite restaurant might turn up some interesting findings. Any local, small to mid-size business might be interested in your assessment. However, it is critical that you always ask for permission before taking pictures.
