Alycia... so sorry for this mess you're having to live with. You've gotten some good suggestions above... I just want you to know that I'm thinking of you.
I think the part about the hog pen is hilarious! It made me laugh. I would put it as close to his property as is legall!
All those trees - that must have been a heck of a lot of work.
I hope you don't have to move. You've invested so much of yourselves into the land already, it would be a shame to leave now. If the land is already paid for, it would be well worth the attorney fees to sort this out and then it takes that burden off of you cause the attorney will handle everything.
Try and do something relaxing for yourself today.... even if only for a little bit.. something you enjoy, ok? You deserve it!
