Burn calories while saving the planet

Today was a good day, because I literally burned calories while helping to save the environment!  For my birthday (which was April 10th), my wonderful boyfriend got me a mountain bike!  And with the current state of our environment (not to mention the price of gas) I decided that at least once a week, I am going to ride my bike to work.  For me, it's 6 miles to work.  It took me 45 minutes, which is basically double what it takes me to drive.  Yeah, I was a little sweaty when I got there, but I brought a change of clothes.  The best part though, is that you also have to ride home...even if you're not in the mood.  So today, I biked for 12 miles, burned a ton of calories, got in my daily workout going to and from work and saved gas money while helping to improve the environment.  If we all rode our bikes to work, or walked, or ran, or roller bladed, or took the bus one time per week, we could really make a difference!
