Well i recently went to Towers and got to Knapp with one of the best in Texas. I made these points,all the rock i worked Sat. was a gift. Tower gave me the agate,and root beer. A buddy named Robert gave me the Perdinales. All rock is raw. I took my shirt off to cool off, but forgot to put it back on the rest of the day. Needless to say i have a burn that matches the agate point.
