I agree with duaut. I have placed one cache that i maintaine all the time.When i go to the cache. I always bring new in the pkg toys and restock the cache.Six dollars at the dollar store buyes alot.I also put alot of things that i make on the computer. stickers, transfers,window clings,calanders,and such. As for trading out on other caches i trade things that i have made a bundled pkg ,wooden coins,sig card,key fobes ,with a email address,that when people take the item to keep they email me. That just makes it that much more fun for me.
