Suspension bridge in the Grand Canyon

We met a man who looked and dressed like Santa Clause on a break from delivering packages. I kid you not, this man had grey hair and a beard to match. He was also wearing red Long Johns. He told us that the suspension bridge was created by Native Americans, hired by the National Parks. Apparently, a tribe of Native Americans have some rights to the land in the Grand Canyon. All of the materials for the bridge were brought in by the mules.
