hi fellow preppers I have a Question, has anyone discussed the benefits of living underground ? Some of our family have been living in an all modern" cave-house" for more than 30 years completely off the grid. some of the advantages are 70 degree temperatures year around no heating or cooling, built in solid rock. water from a well gravity feed to the house at 40 lbs pressure. if there is a thread on this subject i haven't found it. But I am not very good on a computer. open to comments. thank you Mountain scout.
