getting true "north" to even one degree accuracy is harder than it

My QTH is south of San Francisco. I've aligned both of my rotators to
true north using the shadow cast by the towers. On a bright day, summer

narrow, but neither are the patterns of the 3-el Yagis on top, and they
are carefully plumbed to vertical. :)
