A month ago was half also school half term. That may have had more to do with it.Since I became interested in Caravans, on a long motorway journey I tend to look at the caravans I am overtaking and on a long motorway journey of 225 miles a month ago I counted 20 caravans.
I did the same journey this Monday and only counted 2.
Perhaps the fuel costs do have something to do with it ?
