It is good news that the cars have been recovered.
The lessons learnt should be to go prepared, know what you're doing, assess each situation before diving in head long and not drive on land that is not a public right of way unless you've got permission. If you choose to ignore these points and get stuck then the final bit of advice is not to come on sites like this and admit you have been a prat, as everyone will laugh at you.
The 4x4 world has got bad press as the environmentally unfriendly, land trashing bunch of hooligans as it is. Lets not feed them the ammunition they need to prove their arguement.
BTW, on the subject of the guy 'recovering' the Defender with the Disco. I watch some of his other stuff on Youtube last night, incuding his response to some of the comments that others had made. The following words come to mind to describe this individual. "Full of himself", "I am a god", "All attention on me please", "I will destroy this Disco to prove how clever I am", "I am stupid because I don't even recognise how dangerous I am", "I am also stupid because although there is obvious damage to the Disco as a result of the abuse I've just given it, not to mention the damage we can't see, I have stupidly forgotten that the forces that did this damage were totally directed through the Defender as well". He also comments that he has hundreds of pounds of recovery kit, but didn't bring it with him so he had no choice but to do what he did. I supect he is talking bollocks and wouldn't know what to do with said kit if he really did have it. The following complements also come to mind about him. "Cock", "Tw@t", "**** for Brains", "****ing delinquent knob cheese". If there was anyone more deserving of a Darwin Award its him, so long as he doesn't take anyone else with him. If you're reading this mate then I think you get the message.....
