Race Drivin' number 33 question

[ttony_at]

One of my all time favorite Atari arcade game was Race Drivin'.

I'd like to know what the meaning of the number 33 on a barn in

the Regular Stunt Track (that has other racers and on-coming

traffic).

 

When the game starts, turn right around and drive the Wrong Way.

Where the road divides, take the right one and watch for a small barn

at your left. Approach the barn (by driving Off Road) slowly.

When you get close enough, a door will suddenly appear on the barn with

a very bright yellowed circled number {33}.

 

I'd sure like to know what the number 33 signifies.
