I have run across many types of fake rocks. There are a couple of fake rocks that are pretty common. While in Florida, I ran across a homemade fake rock that was particularly difficult to distinguish from the other real ones.
This fake rock is taken from where I work. We've built a new Science Center, which required the removal of a small garden, of which this was a part. I have never seen one of these used for geocaching. Enjoy!
Thanks to my nephews Ryan and Aidan, who helped me set up this cache. Although it may appear close to the trail, you probably want to walk to a clearer part first, and then walk over.
Photos are welcome, but no spoilers, please.
