That story sounds very familiar, similar to one I heard while working at Folsom.
LOL probably every department has the same story.
I can verify the 6’11” white guy. When i was a freshman at Cal poly Pomona I kept the stats for the basketball team. One day the freshman coach asked me to go with his team to chino. Turns out it was youth training school where i eventually wound up working in 1970.
They had the 6’11” white guy and two black guards faster than anyone on our team. The stands were full of CYA wards yelling what they would do to us if we won. It wasn’t even close. We were intimidated and outclassed on the court. None of their guys could get into Cal poly, the coach asked about it, but the two guards went to community college at East La.
