I would avoid "pssst hey buddy" deals and direct land investments. Oil and Gas fraud is the favorite form of investor fraud out there. Instead, I'd invest in oil and energy companies on the stock market. I won't publicly say who to steer clear of. But companies that have their act together (as much as they can - everyone has internal goofyness) include Energen, Devon, Sandridge, and Hess. Little guys like Apex Energy have impressed me as well.
Obviously there is some risk with such an investment. $110/bbl oil is likely over for a while - baring a war. But the secret to success is to do what everyone else is not. Just don't be the guy buying Enron!
Speaking of investments, anyone else note that copper commodity prices are extremely low right now? Between that, low energy prices (transport of heavy things), and the rubble of the ruble (a market price affecting force), I'm thinking sometime around late spring 2015 or so, ammo prices will be at a bottom, and that will be a good time to replenish stockpiles. So I'd shave off a couple grand or so of that investment folio and set it aside for planned long term ammo replenishment budget.
