I have made my piece/peace with the pig.

I will eat about 15 pounds of pork in one year. Tom will eat about 50 pounds the first year, and 5 pounds the second. He will try to smoke the pork for ham and bacon. He will make sausage. He will pay someone to smoke the pork belly for bacon. He will be sick of the whole thing by the end of the first year, but he'll keep the freezer rental because otherwise he'd have to throw away the meat. We will be paying on that freezer for about ten years or until he dies. If I die first, he'll keep paying for the freezer. We will buy a lot of coolers for transporting meat. The coolers will get filthy, and we'll buy a new cooler each time we need one.

On the bright side =

My daughter and her family would probably take a roast on two or three different occasions. If his cousins will take a roast or two that would whittle the amount of pork to a more manageable amount.
I would donate to a food bank, but it's tricky to donate perishable food.
