The Reno Arch, located on Virginia Street, the city's main boulevard, bills Reno as the “Biggest Little City in the World.” While Reno might not be the greenest little city in the world, it does have a laudable list of eco-friendly features. And it starts with the arch itself. The city recently replaced the arch's incandescent lights with LED lights that use 75 percent less electricity . Some of the casinos, restaurants and other attractions are following the city's lead and getting greener. Add this eco-friendly movement to all the area's natural attractions and Reno becomes the best choice for a city-based, Earth-friendly Nevada vacation.
