I usually place caches that are for older kids, (i.e. older than 50), but here's one for the real kids (i.e. younger than 12).
This one is hidden in the middle of town, right beside parking, with only a short bushwack to GZ. It's hidden at "kid-level" and being close to the ground and being agile will be advantageous. See, it really is for kids!
There may be muggles around so be stealthy. Cache is a PB jar with kid-friendly swag.
Have fun!
