As well, I think it best people consider the order in which they do things, change of clothes to the car, supplies to the car, THEN the body, etc, minimize clean up.

Purchasing only a shovel and a 50lb bag of lye at any store may be the sort of thing people remember, especially when they start seeing the missing persons reports on the news. Consider buying something else that screams organic gardening, to paint a different picture. Do they have manure? Perhaps some peat moss and sand? Don’t be afraid to get some alkaline-favoring plants while you’re at it, but don’t get carried away. A single juniper planter will suffice. This can all be dumped elsewhere with far less consideration that pork products; considering that you presumably came from a farm, planting them could also stand as a reason you made a perfectly normal trip in the first place.
