Cuba

As you can see in this preview of the Nature show about the wild animals of Cuba, whenever they show a street scene you see wonderful old US cars of the 50's and 60's. Cuba is a treasure trove of collectible cars.
I think a good thing for Obama to do this week would be to stop the embargo on Cuba. This would be a painless stimulus. Travelers would go to Cuba on US airlines who would rapidly put in flights. Travel agencies would arrange tours. Car collectors would buy cars. And auto makers would find a ready market for the US cars currently sitting unsold in the US. Then we would also export the technology to repair those cars, since the days are long gone when I would lift up the hood of a car and take the air filter apart and bang around on various parts with a hammer and the car would start again. This stroke of a pen could be worth a few billion in stimulus.
