  1. 6:50 AFAIK, we are having sand supply issues. So, where does all this "sand mass" come from? 7:25 Uhhh. No. People are funny. They think sand is everywhere because they saw a picture of sand somewhere. I challenge ANYONE, dig up a 1 cubic yard or cubic meter of any damn where you like. Separate it out, and show me your sand yield. Mind you, I said, ANYWHERE YOU LIKE. Do it. Lol.
