Are there any carpooling options, for either girl? Is there any chance that Fiona could get herself to the dojo on the bus? I tend to think of 12 as "old enough to use public transportation independently," but that's going by the 1980s standards and I know that attitudes have radically changed since I was a kid. (When I was 13, my parents let me wander around London on public transportation by myself. It was great.)
