The town of Rockport has had a hate on for divers for a very very long time.
Years ago (in 1996, when the one concrete dock was federally owned and thus open for all to freely access) we were down there for a Wednesday evening dive, and one of the locals berated us for being there.
He had had an issue with divers the night before who had sat on his dock and woke up his wife. He was in such a rage that he refused to listen to us. We were not the individuals in question. He maintained that we should know the divers (who he said were from Toronto - we were from Ottawa) and tell them to stay off his dock. He was beligerant and offensive and hated divers intensely.
I think he is a fairly typical example of the attitude of the Rockport locals towards divers.
Of course a few ignorant and disrespectul divers have contributed to this situation over the years.
I would have thought the disasterous 2002 and 2003 tourists seasons, plus the addition of a local dive business would have changed their attitude. I guess not.
Over the years the town of Rockport has been chipping away the access for divers to the local waters.
