So, I get my spouse a Monastery fruitcake every year for Yule (she is one of Those Who Love Fruitcake…). I must have ended up on Holy Cross Abbey’s mailing list, because I just got an email about their natural cemetery:

Pricing looks reasonable, their policies are environmentally-friendly, and you do not need to be Catholic or even Christian: “There is not a religious affiliation requirement at Cool Spring, but elements of your specific religious tradition may be incorporated into your burial service.”
