Everyone loves Legos. However, the classical problem with Legos (maybe this applies just to males, especially when more than one male’s hands are in the Lego bucket) is the shortage of wheels. However, help is available. Check out Lego Highway Haulers kit number 4891. One of my male kids spends hours with this kit in a single sitting. It has plans for multiple kinds of vehicles, and you can have some multiple simultaneous vehicles with lots of wheels. Don’t be misled by the picture on the cover, there are plans for about 8 different vehicles from this single kit. And at $10, it doesn’t cost much.
