At the VFW Showcase this year I set up a Pin golf course in the annex. I used 9 EMs (that was all there was).
The short ball times on EMs allowed the nine holes to be played in approximately 40 minutes.
Here is my rule sheet, score card and an example of the cards that were attached to the backglasses of the machine used.
Hope you have as much fun as we did.
PS: I am also working on Pinball Baseball. It is more complex and will take considerably longer to play (;et alone explain)
