A mid-week storm brought several inches of light and fluffy snow to Wellesley, slowing the commute and delaying school for two hours. I might have rolled over and slept in. I should have made moves to shovel the sidewalk and driveway. Instead, I threw my cross-country skis in the back of my trusty Subaru and headed over to Elm Bank reservation at 900 Washington Street for a pristine, virgin-snow nordic skiing experience. Join me on my 45-minute loop through the woods and along the Charles River.
