My kids are naturals at this! We found 4 of the 5 we were looking for. I am pretty sure that the fifth one is on a sandbar in the middle of the river, and if it had been summer (or even spring) I would have waded in to check. Being January though.... it can stay there till May or June!
We had a blast and we are working out plans to hopefully do it again one day next week. (if the weather holds!)
One that we found today was entitled "Engaging Proposal" It was placed by a couple who got engaged on a park bench in one of the local parks. My husband and I just happened to have gotten married in the same spot, so that was pretty cool!
One of the others says it has multiple tracking bugs in it, so we were hoping to find one of those to pass along, but several people have been there in the past week, and the tracking bugs are all gone. We definitely had a blast though, and the kids are already planning a cache of their own!
