Note: Thanks to Clif Bar for sending me Maple Walnut Bars to sample. I absolutely love clif bars. They are one of my favorite marathon workout bars. And snacks too! I am sure I have mentioned this before, but they taste like cookies and not energy bars. The Maple Walnut was AWESOME. As soon as you open the package, you can smell the sweet maple. There are pieces of nuts throughout. Because they are so dense and high in fiber (5 grams of dietary fiber and 4 grams of insoluble!), they fill you up. I recommend this flavor!
