It has arrived. The day that signals Spring as surely as that first robin emerging from a six-foot snowdrift. Truck Day 2015! Tomorrow morning at around 7AM the Red Sox equipment truck will arrive on Yawkey Way to pack up the 20,400 baseballs, 1,100 bats, and 20 cases of bubble gum (along with a bunch of other stuff) and head out to Fort Myers, Florida. Around Noon, Milford's Al Hartz will begin the 1,480-mile trek to warmth. More than most years, this is a needed event. Really needed.
