Quote :- No, all caravans should be burnt.
Well there speaks the voice of reason! A very well reasoned and somewhat 'imflammatory' statement. You might just as well say 'All boats should be burnt!' or 'All trucks should be burnt!'.
Slower moving (slower than you that is) traffic always has been and always will be a pain in the butt, whether its a caravan, an artic, or a RIB on a trailer! Chill out man - if you burnt all their caravans, they might use the insurance money to buy a boat, and get in your way on the water as well as on the road.
I have to go with Red Fox here.... its the buffoons at the controls to blame. Good drivers (whether of caravans or boats) dont give folk hassle - but its the British way - assholes all over the UK have the right to be using the same bit of highway as you - so chill out - live with it - and thank God that you can get out in your boat away from it from time to time.
