Merely arriving at the correct wwwh isn't enough, you must understand why you're there/how you got there.....those who got there and didn't know why, they guessed and guessing will not take you through the steps to solve the clues.
I'm interested in the "why you're there/how you got there" comment. From your perspective is this why Forrest would send you there? or how (methodology) you came to decide that this was WWWH?
Why Fenn sends us there as the start, I'm not sure that matters, he needed to make it work, so it is what it is. How you arrive at the answer that (I believe) is correct, is critically important.
