Your best bet is probably to just throw it in the bank or open a money market account. You can probably find one that'll give you 1 or 2% interest. That or a CD like someone else said.
I'd also say look into getting some foreign currency, but the dollar is weak as fuck right now. I still haven't cashed the checks from my taxes yet, waiting for this exchange rate to improve.
To me stocks seem too risky.
I'd like to get into some of the shit Peter Schiff is talking about, but I'm not real sure how to get that shit started up
