All I inferred was that you can put two five foot bales on a trailer, I didn't say you should or that you should drive on the road with themAnyone who wants to see a picture on how not to transport round bales and especially very solid 5 ft bales on the public highway ( or indeed around a field/farm lane etc ) should take a look at the Devon and Cornwall facebook page... and read about the tragic outcome of doing the above to a cyclist.
