I agree Daddio. Having two kids myself, they like the idea of treasure. As for myself, I like the Hunt, but being a Cub Leader, I always feel for the kids. So, I make it a point to get some quality Stuff for all ages.
A quick trip to the Dollar Store to pick up so Toys and other stuff. I have a supplier of Batteries, and when I go to Conferences, I load up in stuff. This is my material I put back into the Game. If I see a Cache that is Low in Swag, or has crap Swag, I replenish the Cache with New stuff. I also make it a point to Inform the Cache Owner I have done this.
I maintain Two Caches myself, and make sure it has Quality material in it. I am even thinking on awarding the 100th Cacher with a reward.
If we all think the same way, it will be more fun for the Kids, and get them away from the Television and Video Games.
