Chances are the airline crew for your flight arent even in the same city, and wont be untill well after your flight was supposed to land. Usually announced after a "late inbound aircraft" delay and before "engineering requirements" cancellation.

A kickass, high powered rock and roll horn band from Sonora, California. The band was started in 2007 after a jam session in the trombone player's living room, and has since grown to a 10-piece musical force to be reckoned with! They play a variety of styles, including rock, blues, soul, and R&B.

The band includes a rockin rhythm section (bass, drums, guitar, and piano), a powerful horn section (trombone, saxophone, and two trumpets) as well as two fabulous, versatile female lead singers.

Chains Required is a Tuolumne County favorite. They have been featured at events such as the Mother Lode Fair, Sonora Magic of the Night Festival, Concerts in the Park on numerous outdoor stages, and the 2009 Sonora Blues Festival, as well as countless restaurants, private parties/weddings, and other local events. If you see them perform, you won't be able to keep yourself from dancing, whether it's in your chair or out on the dance floor!
"Have you heard of Chains Required? No, I don't mean the road signs, I mean the BAND! They're awesome, you gotta check 'em out!"

"Minimum" computer system specs needed for a computer game to play.

A game will never work if you only meet these requirements. To avoid shit-heavy lag, surpass them like crazy.

Do some fecking research before you buy a game to see what you really need.
"Noob, ignore the system requirements. 512 RAM is nothing, everyone knows Battlefield 2 needs 2 gigs to run properly."

The absurd concept of defining something that must be, when it might not.
