That is an impressive collection of glacial rock. Makes one wonder how far some of them were transported by the ice, before being dropped. Here in the lowcountry, it's all sand. No rocks to be found. Sure makes digging easier.
Gasp! Double gasp! I just gave away my last "lawn rock" to a friend this week. I had a big collection once, but now it will fit in a big laundry basket. I have been downsizing, except for this weekend's load of rocks!
