I've heard a lot about "test gardens", especially from the more experienced MD'ers. I've also read a little on how to make one but they seem to be little more than throw some coins on the ground and then go find them. I've learned so much from just popping in and reading the forum (even the older pages) that it just hit me that this would be the place to find out what's the best way to make a test garden. From what I've read so far this seems to be a really great way to get learn your machine and learn to pinpoint, and that's something I really need to learn with my QD II.
