In celebration of National Public Lands Day, admission fees will be waived at all national parks. Parks are looking forward to an influx of folks coming to visit the national jewels. But there's more to NPLD than just a free visit: Last year 150,000 volunteers turned out at national parks and other public lands, churning out an impressive effort that resulted in new trails and bridges, planted trees, the removal of invasive species, and a host of other services to aid our public lands.Want to get involved? There's still time to find a site near you and volunteer. Check out the National Public Lands Day web site at http://www.publiclandsday.org/.
