The weather was exceptional today and I took advantage of the conditions to kayak a new stretch of the Concord River after work. I put in off Elise Rd. in Billerica and covered 6.6 miles (starting up river) in 95 minutes yielding a 4mph speed without considering stops for photography. With two more strategically placed put ins I will have covered the entire Concord River, including the last mile which is rated as Class 3+/4 whitewater during the spring runoff. A few years ago the family did a whitewater rafting trip over that section which will long be remembered for the capsize that caused Jeanine to swear off whitewater forever.
