Pretty much spent my holidays playing games down at Rosebud.  There was a huge arcade / mini golf joint (actually there were heaps down the peninsula) and lots and lots of 20c coins went into the machines.

What really grinds my gears is years later (before I got back into pinball) the place had been sold and there was a spray painted tarp across the front with come in / make an offer on machines....Doh.   

I remember those places at Rosebud well, one year we stuck 20c to the step at the front and spent the day across the road watching people trying to pick it up about 3 or 4 hours later the owner came out with a shovel and removed it.
