Slot car drag racing
When I was a kid I would always ask for the same thing for my birthday, A race road race set. They wouldn't last long so I was always read for a new one the next year. In 1968 my dad got me a drag strip race set. It came with a Plymouth Roadrunner and a GTX.
There was a blue plastic console at the beginning of the strip and in the console there were two 4 speed stick shifts. The track had numbers on it and to start the race you pushed a button and a Christmas tree would count down. The cars would not move until it reached green and you would have to shift into second when your car reached the track labeled 2 or you would loose power and it would stop. At the end of the track was a catcher that would catch both cars and the flag on it would drop towards the side that won. You would then put the shifter into reverse to bring the car back for the next race.
Found out later that my dad got that race set directly from the dealership where he bought a new 1968 Dodge Coronet. Me, being a kid, I killed it and it likely went into the trash with the rest of the race sets.
About 5 years ago I saw a magazine article entitled "Toys in the Attic" and these things are worth a couple thousand dollars now Arrrghhhh!!!!! But if I still had I probably wouldn't sell it it would be too much fun.
