Talk about a talent hotbed: Curacao is back in the Little League World Series in Williamsport, PA, this week, having won the tough Caribbean Region for the ninth consecutive year. For reasons why, check out this trailer for this upcoming documentary film, “Boys of Summer”–and note the slow, deep practice happening around the 45-second mark. (BTW, here’s the film’s facebook page.)   So far so good: Curacao beat powerhouse Venezuela in their opener yesterday, 2-1.
