Jec,
This is not a question I'd expect from a Texan.
Are you exposed to, or have any liabilites in, any foreign countries? This is where your dollar risk lies.
Domestically, inflation is the only(?) risk to your currency (the dollar). One solution would be index-linked bonds, ie guarantee a fixed return above inflation. Gold is often touted as a hedge against inflation but I think it's too volatile and not something on which to bet your farm/ranch/oil well.
Grant.
