Not sure where to put this one!
If anyone in Wales/on the English border has pigs to sell - including culls - Monmouthshire Livestock Market is having a Christmas prime stock sale on Dec 8. Prizes for the best butcher's pig; best cull boar/sow.
Pig sales are normally first Monday of the month, but there's no market on Dec 1. See the "sales" section of the website for more info.
www.monmouthshiremarket.com I've sold quite a few cull sows and boars there this year and have found it a really good place to do business. Staff are very friendly and helpful (particularly important when you're a bit of a novice and on your tod like me!) and the facilities are really good.
