when you plan your vacaction and get a room at the hotel with all the nice landscape rock, and take your knapping tools along and set up a pit on the hotel balcony. It was pretty nice overlooking the riverwalk in san antonio while knapping. They had full cobbles and nice flakes that all you have to do is presure flake. All of it was rootbeer saw it on the last trip there.. I will never stay anywere else.
