Awesome Hot Wheels Racetrack

This is an epic video. Notice, however, Mom is nowhere to be seen. If she is home, she is sitting in the corner, fuming, deeply disapproving of having this racetrack all over her house. And where can I get awesome track pieces like this? My brothers and I used to play with racetrack just like this as kids, but stopped once Mom discovered that racetrack parts are a valuable weapon with which you could beat a child.
