Farmers can't half be selfish

I've just been crawling at 20 miles per hour in a huge queue of traffic for 7 miles. What's that you say? There must have been some major road works going on or worse a road traffic accident. No, that I could forgive but to trundle your tractor at peak time is pretty selfish in anyone's book. I know they've a job to do and all that but with a little planning they could be a lot more considerate. Oh well, forgive and forget.
