At the tail-end of the summer I went again to the open day at the Museum Collection Centre. The nicest thing is that you get to travel there and back on an old bus. This one was a 1960s bus, I think. I suppose it would have been in service well into the1970s -- it's certainly how I remember bus travel being in the 70s.
On the day I went even the parked traffic seemed obligingly in character too.
