Oop's. Sorry just replace where I mentioned Boston or Mass with north eastern United States. The change has no impact on what I wrote as the same applies. Again, we go from identifying the team with a city or state to a general location in the US. The behavior is the same just the size of the area or acre's. I will not go further in clarifying as it would be kind of obvious and difficult as to why it needs further clarification?? There are a number of books on the subject which are no only informative but rewarding to read.
