Mate of mine runs a charity
He is a pick collector, but has managed to turn his hobby into a very effective charity for cancer. It started off with auctioning picks, but as he got more known bands started donating kit, guitars, back stage passes etc
If you are into rock this might interest you
His latest raffle is for a custom guitar signed by Judas Priest, Metallica, Sting and loads of others - the cost for a ticket is £10 - the prize fund I £10k
