National Parks offer free three-day weekend
PUBLIC LANDS -- National parks will be waiving entrance fees to celebrate Martin Luther King holiday weekend, Jan.14-16.
The Park Service is waiving fees for a total of 17 days in 2012. The Martin Luther King weekend fee waiver is the first scheduled for the year.
Offering free admission to national parks and other federal lands has been offered the past three years as a cost-friendly family vacation option in the economic slump.
