When you're a geocacher...


When you're a geocacher, if you see a bottle ziptied to a mile marker sign you go back to see if it's a geocache.  And you're more than a little surprised to see the bottle is a electret gamma monitor - it detects radon.

    Wow, that is odd. I always associate radon with basements, not with wide open spaces.
