Biden Continues Two-Day Tour Of National Parks

Vice President Joe Biden began a two-day tour of Yellowstone and Grand Canyon national parks on Monday to check in on the improvements from the White House stimulus package, according to the Associated Press.

Biden spoke to roughly 100 park workers, contractors and their families in the Madison Valley of Yellowstone. He said that some of the $750 million in stimulus money has already gone to 800 national park projects, but there was more work to be done.

"For too long our nation's crown jewels have been neglected," Biden said. "Everything we're doing in this park is worthwhile and needed to be done anyway, whether times were good or bad."

As part of his tour Biden stopped at one of Yellowstone's big projects: a $4.7 million replacement of the 50-year-old Madison Wastewater Treatment Plant, which park workers say is bad for the environment (the stimulus-generated plant will hold double the capacity and work more efficiently).

Biden told the AP that he was going to spend the rest of Monday touring Yellowstone with his 16 year-old granddaughter, Naomi. On Tuesday, he will speak from the Grand Canyon's South Rim.
