If you are vexed about the paucity of wonderful number dates recently, wait until November. Primes and a sequence await. 

For the coming week, there is one cool date, 10/16/13 is a halfback day.  Go up 6 from 10 to 16, and come half-way back (3) from 16 to 13.  Last week’s monologue on the end of half-back days neglected to remind the meaning of half back days… it is named after the retirees who move from Pennsylvania, New York or Michigan down to Florida and then move half way back to Tennessee or North Carolina when they find Florida is too hot.
