That lady is either part of the problem or part of the solution... By moving herfe she became part of the problem, if she chooses to return to live in Philly she can become part of the solution. Dont ever restrict the farmers from selling their property, they have bought it and worked hard to pay for it and it is their investment to the future for them..... There are other ways to control urban sprawl, one was is not require so much farmland to build a house on .. You have to give up 4 acres of farmland to build 1 house, that doesnt make much sense to me....
