Ah, what oddly glorious New England spring weather. Much to my wife's amusement, and chagrin, I've resumed my pre-dawn "training" rides on my road bike (though I'm training for nothing in particular): out at 5:30am for a 22-mile loop up through Arlington and Lexington. I'll be doing this two or three times a week. And afterward, when I set out on my commute, gee whiz! I'm ready to chase down every delivery van and school bus I see.
