Monorail

The Robert N. Broadbent Las Vegas Monorail is a mass transit system located on the Las Vegas Strip, in the United States. It is owned and operated by the Las Vegas Monorail Company. For tax purposes, the Monorail is registered as a charity, which is allowed under Nevada law since the Monorail provides a public service. The state of Nevada assisted in bond financing, but otherwise no public money was used in construction, and no future taxpayer obligation will be incurred.
