Bus spotting is a pastime in which one seeks to see all buses in a particular fleet or those produced by a particular manufacturer. A person who engages in these activities is known as a bus spotter, bus fan (Chinese: 巴士迷; popular name in Hong Kong), bus enthu (term in Singapore), bus nut (term popular in the UK) or bus enthusiast (although this term can also cover preservationists). Within the bus industry bus spotters are known as moquettes, from the material used to make the seat coverings. There are many enthusiasts of the bus and coach industry across the globe. Like train and aircraft spotters, bus spotters spend much time outdoors with notepads, cameras or camcorders, monitoring bus routes.
