Can you think of another month with as much going on as April? After all, April sees the beginning of the baseball season, basketball and hockey playoffs, Patriot’s Day and of course the Boston Marathon. Unfortunately, I usually don’t get to witness any of these national holidays. That’s because April also happens to be the one time of year that I can engage my two favorite pastimes: skiing and mountain biking. And I’ll be damned if I’m going to plant my ass on the couch just so I can tell you if Beckett’s fastball has lost its pop.
