Went on this yesterday and it was excellent. had the option to purchase my hackings and now have a freezer full (including the one i had in the garage waiting as homework...)
Andy and his team did a great job and it was very enjoyable. Everyone had their own beast to work on which was good.
A hell of a lot to take in, but it was very satisfying to turn a full carcase into bags of things other than mince and dice.
Very worthwhile for idiots like me.
