Subsequent Events	10. Subsequent Events On October 5, 2011, the Company announced that it will restructure its dry-freight service offerings to improve operating efficiencies. The Company will continue to offer dry-freight options in certain lanes via the Company’s temperature-controlled trailers; however, it will no longer provide dry freight services via a dedicated fleet of dry van trailers. The Company will use the proceeds of these sales, which it anticipates to be approximately $15.5 million, to reduce debt. On October 20, 2011, the Company announced an agreement to sell substantially all trailers and most of the tractors related to our dry-freight services to a major transportation company specializing in these services. Further restructuring associated with this business decision are under review, which will include a reduction in back office work force and will be recorded in the fourth quarter of 2011 along with any additional costs related to the restructuring.
