the simplest toys

It's all gotten so fancy these days, but I reckon kids haven't changed biologically.

But what is all that gameboy and wii doing to developing brains?

Probably still one of the best, and simplest toys, is one that allows the use of imagination. Throw in utility for parent's even better.

Something like the Radio Flyer Ultimate Family Wagon. Or the Radio Flyer Classic Red Wagon.

Doesn't get much simpler than that.
