Sandstone

How are you doing? I am glad you made it down here safely. My name is Sandstone. I am of the Hickory variety native to Central Texas. It is a pleasure to meet you. My dear friend Limestone was delighted by your conversation, and if Limestone likes you, then we will be good friends. Let me know if you find my other friend, Chert. I haven't seen him in a while.
