Don,
I agree with that for the most part, but I've already seen the 'horse' ad during non-golf programming.
Just read on a blog that a PGA life member, Peter Boyce from Ontario, questioned the GCSAA about the ad. He received this reply from Jeff Bollig, Sr. Director, Marketing and Communications for the organization:
"In general, GCSAA takes the position that any commercial depiction of intentional acts damaging golf courses is inapporpriate. This particular ad is consistent with our stance."
I don't know either of these two men, nor do I have first hand knowledge that the exchange actually took place. If it's true I can't see how anyone could dismiss the potential for harm that such an ad could have. The GCSAA doesn't.
p.s. By the way, its also on YouTube and the fraternity of dirt bikers all seem to be aware of his feat. Think that the idiots who do that sort of thing haven't found it?
