Neighbors rock garden, hostas, and digital camera. Only thing that comes out of Texas, is steers and queers, or, so I've heard.
I've also heard the only good thing that comes out of Texas is 35W. But, I doubt that.
This is Minnesota. I live in the Anoka county sand plain, and most rocks that are here, were brought here. I don't have a clue where the rocks came from, but, as a rule of thumb there's no shortage of rocks in MN. Most farmsteads north of the twin cities will let you fill a pickup with them for a few bucks.
Best,
