Twenty historic sites in national parks are vying for $2 million in preservation grants, and the public is invited to vote for their favorite places.

The sites are listed at http://VoteYourPark.org. You can vote once a day for up to five parks of your choice through July 5.

Grant requests range from $97,000 to restore a historic lodge at Yosemite National Park to $250,000 for stabilizing the mooring quays at Pearl Harbor.

Park sites with the most votes will get their requests fully funded. The top seven vote-getters are guaranteed full funding. Other sites will share the balance of the $2 million depending on how many votes they get. Every one of the 20 contenders will also get a $10,000 participation grant.

Voters can also enter a sweepstakes for a chance to win a trip to Yellowstone National Park.

The program, called the Partners in Preservation Campaign, is funded by American Express and the National Trust for Historic Preservation, with National Geographic hosting the VoteYourPark website and promoting the effort on social media. Voters are encouraged to celebrate their favorite sites using #VoteYourPark and @savingplaces on Instagram and Twitter.
