Summary of Significant Accounting Policies [Abstract]

Changes in Allowance for Doubtful Accounts for Trade Accounts Receivable

Accounts receivable: Accounts receivable are recorded at the invoiced amount and do not bear interest.  The allowance for doubtful accounts is the Company's best estimate of the amount of probable credit losses in the Company's existing accounts receivable.  The Company determines the allowance based on historical write-off experience and industry and local economic data.  The Company reviews its allowance for doubtful accounts monthly.  Past due balances meeting specific criteria are reviewed individually for collectability.  All other balances are reviewed on a pooled basis.  Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote.  Accounts receivable are concentrated among customers within the Company's geographic service area and large telecommunications companies.  Changes in the allowance for doubtful accounts for trade accounts receivable for the years ended December 31, 2012, 2011 and 2010 are summarized below (in thousands):

	2012			2011			2010
Balance at beginning of year	$	838		$	460		$	330
Bad debt expense		2,870			3,243			1,437

Recoveries added to allowance		259			439			262
Balance at end of year	$	1,113		$	838		$	460

Changes in Liability for Asset Removal Obligations

Asset retirement obligations: The Company records the fair value of an asset retirement obligation as a liability in the period in which it incurs a legal obligation associated with the retirement of tangible long-lived assets that results from acquisition, construction, development and/or normal use of the assets.  The Company also records a corresponding asset, which is depreciated over the life of the tangible long-lived asset.  Subsequent to the initial measurement of the asset retirement obligation, the obligation is adjusted at the end of each period to reflect the passage of time and changes in the estimated future cash flows underlying the obligation.  The Company records the retirement obligation on towers owned and cell site improvements where there is a legal obligation to remove the tower or cell site improvements and restore the site to its original condition, as required by certain operating leases and applicable zoning ordinances of certain jurisdictions, at the time the Company discontinues its use.  The obligations are estimated and vary based on the size of the towers.  The Company's cost to remove the tower or cell site improvements is amortized over the life of the tower or cell site assets.  Changes in the liability for asset removal obligations for the years ended December 31, 2012, 2011 and 2010 are summarized below (in thousands):

		2012			2011		2010
