You’re right though someone called up Howie and mentioned the bit about the city not wanting them there for First Night at least...even if there were to be no events for First Night there (not sure if there are) some people might go near there and get a negative impression of the city. Similar to how cities that hold political conventions bus the homeless/
vagrants off somewhere else for awhile and try to clean up
litter, etc.
I think First Night runs along the Emerald Necklace (Boston Common and Commonwealth Avenue and takes in the Theater District and Boylston Street. I thought it poetically fitting the the Occupy Boston refuse was spread out at the beginning of the Rose Kennedy Greenway.
