After a thread on here over change from bus fares got very heated, a couple of people said they'd not used buses (and possibly other forms of public transport) for over 10 years.
I find it fairly incredible that you can go so long without going on a bus or use other forms - okay I get that it may be months if you commute by car/bike or walk, but surely most people will make an occasional trip by bus or train across the course of a year for a night out or on a day trip or whatever?
