Answer:
As per Kristy Johnson's letter where she mentioned the clauses of the acceptance of offer, she clearly mentioned that she will consider a response only if it is in written form and is sent through US mail.
Now Judy did as per the clauses and sent her a written acceptance through US mail whereas Michael telephoned her and let her know of her acceptance. If Kristy is adamant on her terms that she clearly mentioned in her letter to both and will stick to her word, then technically, it is Judy's fair right on the Montana interests whereas Michaels telephone call will be discarded as it did not fulfill the terms.
It would be more logical to have an abundant amount of resources than to be in a center of a training route. Thomas Jefferson's Embargo Act of 1807 is an example. America suffered more even though it was meant to punish France and Great Britain. If America had more supplies then they wouldn't have any issue with trading with someone else. America is across the sea so it is hard to believe they were in the center of the training route.
Having a good location is important, but if there isn't enough to trade then that creates more issues. One would be that the area could become a reputation for being unreliable.

Being isolated also means that of there happens to be an issue in the trade then the location is either off the maps or people don't want to there because of the distance and the prices might be able to go up. That's why resources are better than location.
