Restricted Cash [Abstract]
RESTRICTED CASH	5. RESTRICTED CASH At September 30, 2011 and December 31, 2010, we had $10 million and $2.5 million, respectively in a restricted cash account on deposit with our insurance carrier. The restricted cash serves as collateral, in place of an irrevocable stand-by letter of credit, to provide financial assurance that we will fulfill our obligations with respect to cash requirements associated with workers compensation self-insurance. This cash is to remain on deposit with the carrier until all claims have been paid or we provide a letter of credit in lieu of the cash deposit.

The entire disclosure for cash and cash equivalent footnotes, which may include the types of deposits and money market instruments, applicable carrying amounts, restricted amounts and compensating balance arrangements. Cash and equivalents include: (1) currency on hand (2) demand deposits with banks or financial institutions (3) other kinds of accounts that have the general characteristics of demand deposits (4) short-term, highly liquid investments that are both readily convertible to known amounts of cash and so near their maturity that they present insignificant risk of changes in value because of changes in interest rates. Generally, only investments maturing within three months from the date of acquisition qualify.
