Wow they are finally up and for sale. These things all got started when I went to one of my friends here in town that "makes things" and asked if he could make me a something that looked like a real rock, felt like a real rock, could stand up to desert heat and winter cold, and that I could stand on without breaking and was hollow. After a couple of tests, revisions, and suggestions to make them better what you see at the Groundspeak Store is the end result. I guarantee these are far superior to anything you can find at the corner hardware store or something you can make and spray paint.
The original test rock is located here in Albuquerque. The test cache
We purposely hid it in plain site of a large park just to see how long it would last without be accidentally found. I had started the rock as a log only cache but people have been leaving things in it. Its been active for 6 months and so far its been stepped on, rained on, frozen, hit with a weed eater a few times, I threw it down the road once just to see what would happen, ran over, kicked, and still looks like the day it was born and still hasn't accidentally been picked up. I don't know, is that worth $14??
Just to clear something up before it even gets started I'm not associated with Groundspeak or the person who makes these in anyway other then being friends with him and I don't get anything from it. I just gave him an idea and helped him test it.
