Just a tip for anyone who finds themselves with traction problems and therefore unable to extracate their caravan from a grassy or muddy field or loose gravel and there's no-one around to help. Don't hitch the car up in line with the caravan, but at right angles to it, always assuming that space allows. You'll find that you should be able to get moving without further assistance like that, even under quite adverse conditions.
Apologies to the experts who know it all already.
