With so many LA neighborhoods desperate for parks or healthy outdoor activities, a recreation area that includes the forests, as well as San Gabriel River sections near urban neighborhoods, would be a watershed moment.
I encourage everyone, no matter what part of these United States you live in (or even if you live elsewhere), to take a "trip out West" at some point in your life. Get in a car, and go explore everything west of Denver.
Seeing President Obama and his family take in two of the western parks prompted me to strongly encourage everyone -- yes, even you! -- to plan on a trip like this at some point.
