when i was a greenkeeper on my local course i caught the rspca releasing at the side of the course,i asked what the hell are they doing,there response was well they can do no harm on a golf course,i asked them to have a look and showed them the damage to edges of bunkers then the greens they said they understood and no more would be released there, 2 weeks later i caught them again and they still do it now, but hey i cant complain i have to walk my dog alot more now
