I have a lot of friends and family that think I'm crazy but the best investment I have made is about a years worth of supplies that I have stored away in my basement. If you use any products that use corn, soybeans or wheat get them bought NOW! My soybean based frying oil has went up from $19 last year for a 35# jug to $28.90 last week. Every week it jumps 10-25 cents. Corn oil for our kettle corn was $1.69 in the spring of 2011 now it just jumped another 20 cents to $3.19 for a 48oz jug.
I say rather than have your cash in the bank, buy what you need now and tie your money up there. It could even get to where you can't even get your hands on it when you need it.
I think we will see livestock prices drop a little as everyone will liquidate around here due to the extreme drought but hold on to your ass next year. $6 per pound hamburger anyone? Our local store has ribeye on sale this week for $9.99 # for crying out loud!
Maybe we should start a vegetarian recipe forum??
