I remember, and I have to admit that this is a bit vague, we had a consultant at a local hospital. When he heard that it was going to be closed he started to scream and shout and, if I remember correctly and I'm open to correction on this, he not only stirred up enough local feeling that the hospital remained open, when it came to elections he became the local MP, because the local people were so impressed they voted for him and not the usual candidates.

Now that shows that one person on their own can make a hugh difference, but as Ruth says, you have to get out there and make yourself known and your voice heard, not sit tapping away on a keyboard.
