Technically, I suppose these aren't actually trailers. They don't have wheels. They are shipping containers, stacked up in New Greenham Park, the industrial park that was created on the built-up area of the former USAF base at Greenham Common, Newbury. The view point is from Greenham Common itself, from the heathland area that used to be the runways.
The painting was done from a photograph; I liked the contrast between the bright, artificial colours of the containers and the scrubby greens and browns of the heath. I've brightened the colours a little compared to the photograph (which was taken on a cloudy day) so that they reflect my memory of the scene better.
