Another Class 3

I found another class 3! She smoked for 22 years and hasn't had a cleaning for about 10 years. I scaled one quad and her calculus is sooo tenacious. I was pulling as hard as I could and it would not come off. My arm hurt so bad after just one quad. I ended up giving my other class 3 to Tiauna because she still needed 3 quads of a class 3.
