He smiles at her and says. "It is the right thing to do." He prepares for the dyno contest and test and tune.  As he waits for the arrival of the racers for the next days event and random entrants he begins repairs on different engines and rc vehicles.  After a minute or 2 of waiting he gets a young customer coming in. "Excuse me.  I am looking for a slot car set." The kid says. "What kind would you like?  We have up to a 13 scale mile track." The kid looks on with surprise. "How much is that one?" He thinks. "Like 600, it is a 6 lane track and allows up to 12 cars to run at one time.  Fully programmable cars, they all have their own distinct capabilities though, the 600 only includes 2 cars.  You have to buy the rest separately." He looks at his money. "What can 250 get me?" He smiles and picks up a track and says. "5 Scale miles and 2 cars.  This one is actually a 4 lane with 8 possible cars to run." The kid smiles and nods. "That is it." He rings the kid up and sends him on his way.
