I would agree. If you are in California, Chicago, New York City, or Washington DC it is simply not an option at this time. Practically, it is easy and painless to choose a concealed carry firearm. But politically and legally, in a handful of places, you are just out of luck and it probably isn't worth the effort to even try. Unless you are "trying" for all the people confined to those areas and are willing to challange their current laws in the courts. This does work, but it takes time.
