Big deal. It is winter time. It always rains and snows in winter. Media makes such a big deal of it.

It's a slow news day, and they have to do something to sell advertizing.

It's become apparent that the Patch will write what they want to write and not what we as readers want to read. I subscribed to this because I want to read about what's going on in my community after, all it's called "DIAMOND BAR-WALNUT PATCH" Unfortunately as of late the Articles have been anything but. I can get all of this recent information by watching my local news station or reading the LA Times. Hopefully you guys can get back to reporting local community events.
