What's the first thing you do when you get to Las Vegas? Set up the tripod in the airport parking garage for plane trails, of course. Departures seemed to be on 19 which didn't line up with the Strip, so I shot arrivals on 19 instead. There are also some faint trails from helicopters giving tours.
The car trails on the right are taxis queuing up for the one taxi stand. It was an impressive operation.
