I have lived in the same spot for 38 yrs. In 2004 I put a mobile home in and it initially set exactly north and south. Was messing with a compass on my phone a few weeks ago and noticed notth being more to the left, which would be more west. I got a a military issued compass and confirmed with it. According to my compasses, magnetic north has shifted towards the west in my area and quite a bit. I did read somewhere awhile back that the earth was past the degrees for the point of no return and supposedly once we hit another certain degree point, the earth will flip, I guess basically on its end you could say. Ill post a pic of my compass and where north should be in my area when it gets daylight. Its really no proof for anyone else but ill show y'all.
