As has been wisely said many times here: Take a break from "news." (TV, radio, Internet).
That's one of the benefits of camping for me -- news blackout.
And when I get home from camping (50 nights last year) I've found that I never missed a thing that I could do anything about.
Day after day of The CBS Evening Bad News, CNN's latest missing child case and FOX's morning L.A. car chase, etcetera, is a recipe for despair and paranoia.
With all the cable channels it seems to me there would be a market for The Evening Good News.
