I am commuting with the kids 30 miles a day. The 3 and 5 YO in a burley trailer both ways and a 7YO on a tandem we built on the to home trip in the afternoon. We broke the chain on the tandem yesterday on a steep hill and I was telling some co-workers. They all jumped on the, "Get a car" band wagon even saying the kids would be safer.
I still need to figure out a solution for next week, it is more than just the chain, guess I am a little deflated.
