My son and I have been playing it. We go to parks, he finds the Pokemon, I find the caches, we both get some physical activity and the baby gets to see the sights or maybe run around as well. I don't feel as conspicious geocaching because I figure everyone else thinks I am playing Pokemon. Heck, sometimes I am. I really want some developers or gc.com to make a hybrid application that uses augmented reality for geocaching. It would be awesome if the cache appeared before you on your screen like the pokemon, and then you had to do something to open it, and then when you did, the caches had some kind of cool digital swag that you could collect, pass along, or use for some exchange to become more powerful in the game, like what happens when you go to pokestops.
