We've done with the boys for years now. They call it treasure hunting.
Well, the two younger boys call it treasure hunting. The older one DID, but now he's too old for that silliness, so he calls it geocaching.
Whatever, he still gets super excited when he finds one! lol.
We set out yesterday afternoon to find five. We found four of them. An unpredicted rain storm started moving in and the clouds messed up the GPS plus we're not tempting lightning, so we called it a day and headed home.
The neatest 'treasure' we saw in one yesterday, IMO, was a sand dollar.
I also found someone's sun glasses and left them near the parking area in hopes they might come back and look for them, but that doesn't count. lol
