MELISSA BLOCK, host: The National Park Service is proposing new rules for corporate      sponsorship of park projects and facilities.  That means if companies      donate money, they might be recognized by name on the site of the park.</s>ROBERT SIEGEL, host: The proposal does not mean that the actual parks will soon sport      corporate names, but critics are afraid that we soon might see something      like, `The official beer of Yosemite.'</s>MELISSA BLOCK, host: The Department of the Interior says that any corporate      recognition will be tasteful, things like engraved bricks in a walkway or      plaques with names of donors.</s>ROBERT SIEGEL, host: But it's just too easy to imagine the possibilities for      something more expansive.</s>MELISSA BLOCK, host: There could be, `Thermos, official sponsor of Hot Springs      National Park.'</s>ROBERT SIEGEL, host: Or the AARP, on behalf of the endurance of the venerable, could      lend its support and name to the Petrified Forest National Park.</s>MELISSA BLOCK, host: How about the Lincoln Memorial becoming the Lincoln Mercury      Memorial? Or, in a daring move, Toyota could sponsor Ford's Theatre here      in Washington.</s>ROBERT SIEGEL, host: Martha Stewart's corporation might sponsor Alcatraz Island      National Park.</s>MELISSA BLOCK, host: Or what about Clearasil's Crater Lake National Park?  Rogaine      could help out Yosemite's Half Dome.</s>ROBERT SIEGEL, host: And just in time for the holidays, Chimney Rock National      Historic Site could be brought to you by the St. Nicholas Center, devoted      to discovering the truth about Santa.
The National Park Service says it's planning to seek corporate sponsorship for park projects and facilities. That means that corporate donors could secure naming rights to park attractions. Critics of the proposed policy are worried about just how far this plan will go.
