I've never hunted an X zone and probably never will but they are managed for quality bucks. They aren't over the counter tags though and may take a couple years or more to draw. If you live in the San Fernando Valley, why aren't you looking at these zones;
A-31- Los Angeles Archery Either Sex
D-11- Angeles Natl. Forest
D-14- San Bernardino Natl. Forest
There have been some very big bucks taken out of these areas. Just got to put in the effort. Bucks aren't chained to trees in the X zones. They get big but still require hunter effort.
