Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]

1.     General

Basis of Presentation

The accompanying unaudited interim Condensed Consolidated Financial Statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information.  We believe such statements include all adjustments (consisting only of normal recurring adjustments) necessary for the fair presentation of our financial position, results of operations and cash flows at the dates and for the periods indicated.  Pursuant to the requirements of the Securities and Exchange Commission (SEC) applicable to quarterly reports on Form 10-Q, the accompanying financial statements do not include all disclosures required by GAAP for annual financial statements.  While we believe the disclosures presented are adequate to make the information not misleading, these unaudited interim Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and related notes included in our Annual Report on Form 10-K for the year ended December 31, 2012.  Operating results for the periods presented in this report are not necessarily indicative of the results that may be expected for the calendar year ending December 31, 2013, or any other interim period.  Our business is somewhat seasonal with slightly higher freight volumes typically experienced during August through early November in our full-load freight transportation business.
