How many wagon trains are still around?

A wagon train is a group of wagons, typically covered, traveling together along a shared route. Typically used for mutual benefit and assistance, the wagon train fell out of use with the introduction of more secure and reliable forms of transit, such as cars and track-based rail lines. Today, wagon trains are used to provide tourists and travelers with an "authentic wild-west" experience. An accurate count of how many wagon trains are currently in existence would be difficult to obtain.
