Looks like a great find RW.
I like Todds and Esshups advice on letting a pro manage it till you are there full time. Greg may even be able to assign your brother with some "to-do lists" that he would enjoy if he fishes. In four years with proper management, it could be spectacular. If you don't decide to do that, then you should let the guys here know that. I bet there are many things you should/could start doing.
Congratulations, keep it fun...
