Marni, when did you live in Acton? I have lived in the area for about 20 years, most of it in Boxborough. My kids went to A-B.
I know all about getting up at the "butt crack of dawn," to exercise. When I lived in AZ I would go out and walk at 5 AM, or go to the gym.
Off to ride to the Stow Airfield for a delicious breakfast at the cafe.... although right now I am wondering how I will feel riding home 12 or so miles, after eating. Before I moved to Concord, it was 3 miles.
