My friends and I have discovered a new sport. Road Bowling has apparently been popular in Ireland for some time, but there are certainly some devotees in the USA. We've been doing it on Vashon Island, WA. Traditionally the game is more like golf, taking the fewest throws to get the longest distance. We usually go for distance and occasionally use some beer cans as pins. The iron balls are two pounds. It's best to have a metal detector to find balls that fly off the road. Also, a truck with a tailgate for pizza-n-beer purposes is recommended.
