Sadly it's very true. I've been involved in a number of volenteer organisations both inside and outside of transport, and in both a volenteer and paid capacity, and with one exception (and that's probably because I only get over a few times a year) I've always found the politics and infighting too much to handle, and it's put me off getting involved in more. It's one thing when it's paid work, but when you are giving your own time it is so easy just to walk away and not look back. It often goes both ways too, management can be the problem but you also get volenteers who are too far up themselves.
