Does anyone know of a way to make or get rocks to throw quickly and cheaply?  It would be greatly appreciated.

The beach is always a good place to look, if there are any near you.  Always got big round stones.  Perfect.  Also, on the banks of rivers are good, although they tend to be slightly more elliptical.  And there are loads of articles etc on how to make glandes, and cement balls, and all that.  That is about all I can think of at the moment.  If you aren't near the coast, look for some rivers or streams.

And here I am thinking "golf balls are everywhere! who would sell golf balls on ebay?" 3061 listings!!! LOL!

Railroad tracks yield plenty of rocks. They're somewhat angular, giving a fun buzzing sound as they fly away...

Look around you......perhaps you can find the materials to construct some sort of rudimentary lathe.......

My little brother has been slinging ice cubes. They tend to stick to the leather pouch slightly after a few warm up shots We started working on ice molds made from plastic easter eggs, but we're still in the R&D phase. At least the ammo is almost free and you don't have to go down range to retreive ammo... I think he's come up with "random irrigation" and if nothing else it gets him away from silly computer games from time to time.

I can tell you from experience that water balloons can one of the most entertaining ammo choices.  I have slung  some hefty sized balls of water over 200 yrds.   I remember once slinging one up a hill as a mother and daughter were nearing the top on a hike and thinking that there would be absolutely no danger as this rather large water balloon would most likely burst in the pocket, much less make it that far.   Boy was I wrong.   The balloon seemed to act as a long range wireless defibrillator which jump started my frozen heart muscle as the balloon neared the 2 females.   It impacted about 2 feet from the girl's feet and got them both wet!  The strange thing was....they both kept walking with only a cursory glance over the shoulder.   I think that they must've assumed the deed was done by hand from someone hiding along the tree line parallel to their path.   The sling is a vastly superior device for launching water balloons than those overpriced, 3 man rubber slingshots which only launch egg sized water balloons!   I would hate to get hit in the chest with a larger one....it would bowl an male adult over with relative ease! 8)

Tech,
Looks like I need to try fooling with water baloons as sling ammo. In collage we built a 6 man sling shot for fireing baloons full of old guacamoily(sp) that were about the size of a large orange. But that is another story...
Being serious camper I always carry marshmellows and anisse oil for other campers that bug me. Both attract racoons, possems, skunks and alot of other critters. Needless to say a camping area can be cleared of idiots in one night with simple baiting  8).
I can see it now... A group of yo-yo's hearing some things that go thump and or piff  in the night, then the russling a while later when the camp gets invaded by "scarry woodland animals". All done at long range by a guy with a sling , some special ammo and a loathing for games like "flashlight tag"...
