RAISING MONEY..

It has been put to me about ways and means ofraising money from club events to go towardsour annual donation to the British Heart Foun-dation. One of the ideas is some sort ofSponsership on say "one of our Contests" oreven "on a Special Event" by tryrng to guess thetotal distance worked, number of Contacts,etc.... So what do you think ? Have any of youany further ideas ? If the answer is YES then getin touch with Stevie GM0WRY who has asreedto try and get something set up. ( He is fed up The above picture was obtained from the internet and is

giving all his work mates money so he wants 1s reproduced hsre as an experiment. Although not in colour

get money out of them !ll! ) come on then g"t L.ll"^Y,t-:n: *tttry that can be obtained using this new

you brains working and pass on rhose td.*.. ""' irffITr,lilflffirt ;l:"-T'*"ffi f*t#;',ffiBob GM4UyZ @ GBTEDN to me-for others to see? How about letting us see for
