The mega retweet
We scour Twitter to highlight a standout travel tweet.

"Homeland Security replaced its color alert system. From now on, threats will be classified as 'scary,' 'very scary,' or 'very very scary.'"- @MrsRupertPupkin

Replacing the US Department of Homeland Security's rainbow of warning are two categories: imminent threat or elevated threat. Citizens can be notified, of course, by following a Twitter account (@NTASAlerts) and Facebook fan page. The Homeland Security social media operators have yet to post an update on either account. In this case, that's a good sign, right?
