graylling: For anyone who hasn't found this one yet I hate to be the bearer of bad news but it's gone. I have archived the SE corner as it keeps disappearing and I'm getting tired of replacing it. That means that the puzzle can no longer be solved as you need info from all 4 corners. In my travels I also checked on the final and found that it is no longer where I placed it. It may be around there somewhere but no where I could find it. That leaves me no option but to archive it too.
The other 3 corners will still remain as regular caches but the clues won't mean anything. I want to thank everyone who has searched for this one over the years. It's been fun keeping it going but it's time has come.
