I am translating a 30-year anniversary book for a company in Austria. As part of their activities they show a photo of employees playing a game of "Asphaltbahnschiessen". The players are standing on an asphalt [possibly rectangular] surface and there are pins of some type on the ground... Any ideas? I am only getting three hits on Google and none of them were helpful.

Thanks in advance for your help!
