thanks guys. I've added a little bit each spring for the last few years. I collected a lot of rocks from work here and there. My boss built a new house a couple years ago and I was working there for about a year... Yeah it's a big house. But he had loads and loads of dirt brought in, and I would go out and pick rocks out of the piles and bring them home in buckets. So yeah, because I am a carpenter I am able to find the odd rock here and there. It's funny because now I'm looking for rocks that have a nice shape to them so I can bring it home.
Heres a couple more pics
