Most people have very individual views on Charity and fundraising so I'll keep this simple. As a group we have the potential (particularly at meets) to sling a couple of quid in a pot and direct that money to a charity of our choice, that may be a bike related charity (Air Ambulance etc.) or perhaps for our Armed Forces.
There are numerous charities and many people will support none, some will support a single charity for very personal reasons and some will support as many as they can.
I don't want to get into a debate about it because I'm sure it will end in tears. So.... a charity will be nominated prior to any organised event, at that event a hat (or similar receptacle) will be passed for a completely voluntary contribution, there will be absolutely no obligation or question if people choose not to donate.
Simples.
