I like to pick up a handful of .99 cent first aid kits for swag items, or foreign coins of some sort or similar, as mentioned earlier. I get these real cheap from a local coin dealer. And as always, I also have tons of the typical Kid toys or collectibles, I try to leave a little something for the adults as well as the kids. Even if I don't take anything, or if the cache is pretty much empty or has just junk, I always try to top it off, especially with kid friendly items. Nothing beats the look on my sons face when the container is loaded up with treasure.
Stay safe,
