Southern California is a difficult place. There is a large population and a wonderful climate.
But, for that reason there are many venues competing for the public's time and dollar. On any given Saturday or Sunday besides the usual beaches, deserts, or mountains there are many museums, ball games, aquariums, gardens and amusement parks. Add to that the many other special events. There are many things for people to do.
Try getting your word out in a media market that has many TV stations, radio stations, and newspapers over several counties.
