Bus spotting is a kind of activity when a person wants to find and to see some particular buses in some definite fleet or made by a particular manufacturer. Such person is called a bus fan or a bus spotter. Bus spotters spend much of their time with cameras, notepads, trying to monitor a definite bus route. As a rule bus spotters are keen in unusual liveries and they can track an interesting vehicle through its whole life, being aware of its fleet numbers, owners and renewed mechanical parts. Bus spotting is very popular in Hong Kong and there you can find a great number of bus societies. As a rule bus spotters are not only fond of taking photos of buses, but also they enjoy riding on them.
