i wasn't going to contribute to this thread, but i feel the need to defend Arthur.
The main point is that Arthur isn't the least bit "weird". The tv program that featured him was tied to a specific agenda, and was very misleading.
Had the producer decided to feature Arthur as the man of many interests, who, to use maggots example, orienteers, who is passionate about wildlife in general, ornithology in particular, and enthusiastic about ecological matters generally, then he would perhaps have come across as the fascinating human being that he actually is. Eccentric? certainly. Weird? absolutely not. Still, its not the first time individuals have been portrayed by the mass media as other than what they actually are, and it did make enjoyable TV. But not honest or accurate.
Bodmin is a lovely little town. Some of my schooling was done there, and my old Dad psychiatric nursed some very sad cases at St Lawrence's over a long period. i think its closure damaged the town and continues to injure the interests of many mentally ill people who today just roam about more or less abandoned by an increasingly cruel system whose only concern is £sd.
My advice is to get to the Bodmin moors for a biking holiday. Its absolutely superb away from the regularly beaten track. Highly recommended.
