This was my second trip to this cache. I wish there were more Wherigo adventures like this one around. This cache is set up in Greenvilles Historic Falls Park which creates a picturesque backdrop for the games storyline. If you like the storyline type cache hunts, you will enjoy playing this cartridge and finding this cache. Only available on Geocaching.Com, the REAL geocaching website. It says so in the name…
