"Bedford is only 2 miles east of the CIT NDB ...". ......I did put in a caveat in my posting "(apols if this is a poor example, I don't have a half-mil map to hand to use a valid case but it hopefully makes the point)". I was simply trying to choose somewhere (off the top of my head) which would demonstrate that there's often several valid air traffic units with whom aircraft could be in contact with.
