I ride mostly on bike paths for my commute to and from work and school. Some days I do both work and school rides for 50 miles. One month last summer I road 1050 miles in one month.
On the weekends I go riding with friends. We only have one small car (a Scion) w/ a bike rack so commuting is a part of every day life. With the Burley trailer, commuting with the 2 year old is not a problem.
