I'm not, but I do know that my father mapped church property all over the US for at least 7 years. Someone else took over the job when he left.
he rode around the borders of church owned land on a four wheeler that had a satellite dish attached to it. Can you imagine doing that day after day for 7 years!? That is a tiny clue to how much land the church has.
He mostly did farm land. Possibly land that local meeting houses and temples were on. I'm not sure on that one.
Too bad he's still TBM. He could probably answer most of your questions.
I'm new to the forum (need to get a bio posted soon), but I've been a lurker for about 6 months. I decided to finally register when I saw your post. I have a degree in surveying and geographic information systems. I work in land development. I'll send you an e-mail.
