Park goers and officials getting ready for President Obama's visit to Yosemite

YOSEMITE NATIONAL PARK (KFSN) -- President Barack Obama is celebrating America's National Parks as the system nears its 100th birthday.

Friday the First Family made its first stop on a Father's Day weekend getaway. They visited Carlsbad Caverns National Park in New Mexico and Saturday they will visit Yosemite National Park.

The president plans to stay in Yosemite National Park through the weekend.

Park officials are warning visitors of heavy traffic congestion, full parking lots, and several short-term area closures during the President's visit.

Along with talking about preserving the nation's natural beauty in places like Yosemite, the president will stress the economic benefits National Parks provide.

The white house said every dollar spent in a National Park moves through the economy ten times over.

Visitors to Yosemite pump millions into the park and the local economy. Along with camping and sightseeing, there's shopping. And park visitors are even finding souvenirs from this presidential visit.

"I think it's a wonderful thing to see a president who's done a lot of great things for our country and is coming do to something that makes our country great," said Terri Singleton, San Francisco Bay Area.

During an address on Saturday morning, the President is expected to emphasize the need to spend more money to preserve Yosemite and other parks and natural sites.

Something the Yosemite visitors we spoke with seemed to agree with.

"Any help, any federal money they can throw this way. The more dollars that go here, the nicer it stays," said Michael Jost, Buffalo, New York.

"I completely agree with the President on that. I think National Parks are one of the greatest treasures we have in the nation and I'm glad he supports that," said Patrick Tucker, Hawaii.

The Presidents goal is to have as much of a family vacation, with his wife and daughters as possible.
