Eclipse path of totality begins in Oregon
The day of what promises to be the most viewed eclipse ever is here. NBC national correspondent Miguel Almaguer is in Madras, Oregon, where thousands have converged at the first stop on the path of totality; Kerry Sander reports from Carbondale, Illinois, where the dark will last longest, and Tom Costello is on the deck of the USS Yorktown in Mount Pleasant, South Carolina, the last stop along the path of totality.
