Pretty decent as this starts to add up. Don't get me onto golf balls as we used to live next door with a boundary wall running along the 13th par 5. On average when golf was being played anywhere between 30 and 50 golf balls per day would end up on the property. There was some close misses like one landed next to me whilst I was in the swimming pool. Another embedded itself into the thatched roof but the pool was the main catchment area. I gave most of them away, but reckon I have a few thousand lying around somewhere.
