I am just sitting here thinking of what kind of woman would be married to this man and have children with him. Should I feel sorry for her or is she an utter twat like CF?
What sort of people would be friends with this CF? 'That woman locked your car in when you dickishly parked on her property so let's drive to her place at 10pm and try to figure out how to break it out instead of knocking, apologising and ending this in a civilised way.'
If he is regularly driving past your house OP then he must have someone driving him because if by chance your gate is open then who would drive the other car back? (need 2 drivers) Who on earth would say 'I have absolutely nothing else to do so yes CF I'll drive you around to the OP's property every few hours day and night on the off chance she's left the gates open'.
I wonder what CF is telling his wife and mates who are tagging him on FB? If OP has explained the situation on FB then how can CF come back with any plausible excuses?? I feel bad for CF's children. Woman comes out 'you can't park here' CF does anyways 'It's ok kids, we're special and can do whatever we want' then finds gate locked 'It's ok kids, climb through onto the private property and get to the car don't mind the dogs guarding private property' and then somehow get back to their own property minus the car 'it's ok kids that bitch locked us in it's all her fault' same story to the wife and friends 'sorry kids we can't go to the carvery today because that bitch won't allow us to get our car'.
Imagine going through life not taking responsibility for yourself and teaching your children to do the same. 
I completely agree with pp. Phone the FC today and tell them CF is blocking access and has been told multiple times to move the car. Don't post on here or FB that FC is coming to damage move the car out of their way. (Post here afterwards, with photos!!:)
I'm also thinking in some private car parks there are signs saying 'Driver parks at own risk we can't be responsible for cars left here' or something so could you (or the pp who has the abandoned car at the golf club) put a sign that says something like 'cars left here will be towed at owner's expense'?
When is your next hay delivery OP? CF is blocking access to you feeding your horses if the FC don't turn up first?
I can't believe people can park on private land and there is nothing the land owner can do. Can you phone the media OP? Get them to do a story about CF parking on private land and the limitations of the land owners? CF who is very concerned about appearances will undoubtedly not be pleased with his car being flashed all over the television and the start of a petition to have the laws changed? (I'd sign the petition and contact my local MP to support a law change if it comes to that!:)
