The bus doesn't cost a penny. I fon't know what te fuss is about. lol
I also have a freedom pass for London, which is like an oyster card (Octapus???) and I can use any bus overland or underground train in the city, also free. When I was in London for the first 6 months of this year I was saving over£100 a month.

Trams are a nightmare, no one who has been to Crawley for instance could ever advocate street trams
