Is leaving a time capsule above ground risking the contents?
Not if you take the precautions we outline. Remember, there is a strong adventure incentive attached to this …along with a degree of risk. You could cache the same small items in a cardboard box in your attic for a few decades, but your younger family members would never experience the fun of retrieving it. Frankly, searching in a remote area of the American wilderness to find an exact location your parents or grandparents may have visited in the past can be a very uplifting moment in your life. Finding a few insignificant pieces of memories placed in that remote and secret location… just for you… can elevate the experience to priceless. Remember, in the sport of geocaching, there are already hundreds of thousands of above ground caches that have been placed worldwide. But people accept risks as part of the geocaching adventure as well.
