So, due to diligent work on the part of the Troll, no car payments for the past couple of years, and due to the Troll finally catching a break, he's accumulated a significant amount of savings. Not take-a-year-off kind of savings but enough that I want to get it out of a regular savings account.

Here's the thing. Every other time in my life this has happened, attempts to invest the money in anything more complicated than a CD or a money market account has quickly lead to massive erosion of the principal. So much so that it took quite a lot of soothing talk just to get me to enroll in my company's 401k.

And, of course, the stock market is currently horrible.

So what do I do? I put the money in an Ing account last year, when they were offering 4.5%, but that has since fallen to something like 3%.

Liquidity is important because, I assume, Troll Jr. will want to go to college in 2 years.

Is there anything I can do with this cash or should I just leave it parked?
