There is a thread on here that has outlined some of the problems in the past. As you say the majority are probably decent folk who would be nice to you as long as you are nice to them. There seemed to be some local councillor that was stirring it up and I suppose a few locals don't reflect the views of the vast majority of folk there, of which there are most likely to be fellow cyclists.
I remember a few years ago, in a little village nearby there is a local football club, that play to a decent standard on a Saturday. They have a clubhouse with a bar etc. The locals were complaining about cars parking in the village etc. It was odd how a woman on the local council kept trying to cause the club problems and she lived in another village. Her friend lived in the village in question, so it was quite apparent what was going on there. The team have been there for years and provide a facility for people and the vast majority haven't got a problem
