What does $2 buy?

I took the boys (Eli and Nathan) to a couple of thrift stores today (I like their lines of clothing...cheap and preshrunk). They found one of those electric race tracks with the "guns" that make the cars go for $2. They had both earned some money recently for doing extra chores, so I told them they could buy it if that's what they wanted to spend their money on. I had one as a kid and had a blast.

For $2, we're hoping it keeps them entertained for a few days. Then, if they lose interest, we don't have to feel bad about getting rid of it (or setting it up in our room to play after we put the boys to bed).
