FNC's Shep Smith: If We Taxed Inaugural Parade Carbon, Would Be Expensive

"The thing I noticed... the smell change.  You can smell the fuel. There's a very large carbon footprint out here. Were we taxing this, it would be expensive," Fox New Channel anchor Shepard Smith quipped to colleague Neil Cavuto, in live coverage from Washington shortly before 4 p.m. on Inauguration Day.

Smith and Cavuto were watching the slow-moving presidential limousine make its way down Pennsylvania Avenue to the presidential parade reviewing stand.
