This is just my opinion, The size of what your feature determines how far it can be seen FROM, I believe that when you can see the cross then you are in Church, if it is a place of worship then there should be places for folks to sit and more for you to ponder, there should be other churches at 12.5 intervals 5 leagues East / West / North / South, don't expect any short cuts, as an example GO 2.5 leagues west, then go 2.5 leagues north or south to find another, or Go North from there 5 leagues should be another church, this was determined be a system that worked using a computer and different methods that was known by Tinman and my self on a rainy day in Stillwell Ok on old Church sites that we knew starting at Spanish Fort Texas. We posted the information on another site.
