Sunday 1st June is the 10th Annual Slough & Windsor Bus Running Day. This is organised by Amersham & District Motorbus Societyhttp://www.amershammotorbussociety.co.uk/
They operate as many of the old London Transport Green Line as possible using vintage buses. Predominately RT's RM's & RF's, but as it is the 10th Anniversary this year there may be something more interesting turn up.
It is a great day out, and all bus rides are free.
I am not a member of the Amersham & District Motorbus Society, I just think that it is a great day out, and a chance to ride on the buses of old
