We have two sons who spend the majority of their days rolling, ramping, and racing their many cars all over the house. We found the perfect racetrack for them. It is a piece of vinyl soffit found at any home improvement store in the siding section for about $12. It has three lanes and bends slightly to give the perfect incline. It’s 12″ wide and 12′ long and can be placed anywhere. My boys have had it on our outside front steps, our stairs inside, and leaned up against our couch. They have had so much fun sending their cars down the track and watching them race down. The best part is that it is thin so can be stored anywhere, it’s very inexpensive, and it keeps the boys busy for hours!
