Mark Box used to work out at Berkeley, YMCA gym. He was a tall about 6′ 7-8′ black combined Red American guy. He has a BS in mathematics from UC, Berkeley.
We become friendly. I think he could do weight more than Indian champions could do. Once I was walking with him towards Berkeley Downtown Bart station. He commented look at that car. That was a policeman in that police car. He told me now he will follow me(Mark). I wondered why.
We walked to Berkeley Downtown BART station, took a left turn, there was an Italian coffee shop just 1-2 blocks away. We sat there and started having coffee.
After 5 minutes or so, the entrance door opened, and there was he, the policeman we saw earlier. He took a seat close to us.
