Be patient and enjoy your rock Tumblr.
My rock Tumblr is running right now full of different types of rock. Two more days and I will open it at the end of cycle one, and I am anxious to do so. I plan to take pictures after each cycle, hoping that will help me learn how each rock tumbles. It’s a fun hobby even for an 80-year-old who likes to go to the beach and gather rocks.
