Mark your calendars! This summer, all national parks around the country will open their gates and offer free admission to the public — but you have to know when and where to go. Hopefully, you caught our tip a few weeks ago and headed out for a fee-free weekend in early June. If you missed that one, don't worry, there are plenty more to come.
Here is a list of the remaining fee-free days at national parks this year:
Aug. 14-15, 2010
Sept. 25, 2010 (Public Lands Day)
Nov. 11, 2010 (Veterans Day)
