Problems: 

The pointing continues to be challenging, but is manageable. This senior citizen may have dementia, and often forgets where he should go. The first target right after the evening zpoint is off more than 3 arcmins. A few zpointings are done throughout the night to keep his dementia from deteriorating. At least, he recognizes his old friend!
