From an old grizzled vet: (1) Take lots of photos; (2) Go to as many games as humanly possible; (3) After games, only talk about baseball if he wants to talk baseball; (4) On academics, don't hesitate to ask questions...and evasive answers are not a good sign; (5) Stay clear of the whiny coach-criticizing parents (yup, they exist in college ball too);(6) Just be there for your son-he will have huge ups and huge downs-and the next 4 years will blow past you faster than a MLB fastball. We're now several years since our youngest finished his college career and I have occasionally heard both sons talk about how nuts their parents were to travel so much, sometimes only to watch a game and then a brief hug and a "bye" as they got on the charter to head back to school...but they felt the love.
