Lights

I was In Castle Douglas this morning, or CD as it is often referred to, when I saw what looked like a caravan and went over to have a look.  It is touring round the UK and is a project run by BBC Radio 4, they are recording conversations in order to give a snapshot of life in the country today.  The coloured lights indicate that a recording was in progress, so I might now listen to some of the conversations on the website.
