Excellent topic.
We are a small club with 4 senior teams and one junior team. It's been largely one of those "stuffy old committees" for a long time, but this year we've had a changing of the guard and are looking for ways to rejuvinate things and bring the teams back to more of a club feeling.
In Australia, we have this exciting legislation called "responsible service of alcohol" outlawing anyone being responsible for their own actions and makes anyone who serves someone a beer legally responsible for anything the buyer does for the next month, which means we cant sell beer or run a legal gauntlet we cant afford.
We are sponsored by a local bowling club for a small amount, which is pretty much the only establishment in the small town bearing the name of our club.
Our fundraising is left one trivia night per year, which have been fun, but with a younger crowd and the absence of grog sales, I fear wont continue to cut the mustard, so these ideas everyone has have been wonderful, particularly fantasy league!
One idea we did come with was "a night at the races" (Australians are mad punters). You get an old race meet on a projector, set up a bookies board, rename the horses to whatever you want, names that take the piss out of your players work well. You can take it as far as you like...... you can run an audio commentary track for the races and set up form guides in booklets. Sell fake money $10 for $1000 etc, at the end of the night, the 3 with the most money win prizes, club keeps the cash. Basically costs nothing except for the prizes..... As blokes get pissed, they bet more and more.
Some of the ideas in this thread are awesome.... Great work guys!
