I'm a definate noob here so take my .02 for what it's worth but I made it a point to pack my swag bag with things that, I believe, others would like to find. This includes both items for children as well as adults. I believe IMHO that after enjoying the hunt (most important) that finding something of interest in the cache is the icing on the cake for both my son and myself. I don't mean that it has to be fancy or expensive but just that some thought was used in picking the item to leave.
