Got to think hard here (a senior moment!) . . .
Son#1 is 35, lives in San Jose, and works as Sr. Tech Writer for Mentor Graphics. He's a gamer, but I don't ask and don't tell. He has 2 kids . . . 4 and 2 . . . big on "Blue's Clues."
Son #2 is a cellist with the Tulsa Philharmonic . . . I think he's 29. He plays mostly sports games (FIFA Soccer, NHL Hockey, Etc.)
I built both of their computers for them. I'm getting specs for their next machines already.
