Related Party Transactions [Abstract]
Related Party Transactions	17. Related Party Transactions In May 2008, we entered into a freight services arrangement with Group Transportation Services Holdings, Inc. (“GTS”), a third party logistics and freight management company. Under this arrangement, which was approved by our Audit Committee on April 29, 2008, GTS manages a portion of our freight and logistics program as well as administers its payments to additional third party freight service providers. In May 2010, GTS merged with Roadrunner Transportation Systems, Inc. (“RRTS”) in connection with the initial public offering of RRTS. Chad M. Utrup, our Chief Financial Officer, was elected to the Board of Directors of RRTS in May 2010. For the six months ended June 30, 2011, we made payments (net of pass through payments to other third party freight service providers) to GTS/RRTS of approximately $0.2 million for these services.
