On or I guess as this is the theme 'enclosed' in the subway. Some times I feel like I spend a lot of my time in transit. Not transitory, but actually on public transit: subways and streetcars and buses of my! I'm been struggling a little bit with the 'enclosed' theme and I wasn't sure if it was becuase I don't *get* claustraphobic or, and more likely, I don't put myself in the situtation where I could *become* claustraphobic. I know routes, times and frequencies and will often choose the road (or subway) less travelled.
