We took some friends' grandson for his first geocaching experience, and his first find was a cache with a few rubber bands, some broken McHappy Meal toys, and a single small piece of lego - talk about disappointing! We were relieved when at the bottom of the cache he found a lanyard which he took. We explained about trading etiquette, and he happily selected some swag from our goody bag to upgrade the cache "so the next kid who finds this will have more choice". We always have a few kid-friendly items with us, even though we don't cache with kids.
Another cache we found recently contained several cards with Mormon religious advertising - not exactly sure what they had been traded even or traded up for...
