This rug has been a staple toy for all three of my boys.They've all enjoyed hours of open-ended play on it. Joe, specifically, has always added airplanes and helicopters to the airport, small animals for a zoo and lots of signs to the roads. We raced our little cars back and forth on it this morning (paying close attention to our signs). I bet if I leave it set up for the day, the older boys will find their way back to it. You can't resist it when it's all set up.
