I remember hearing a few years ago about a plan to move the fire station and turn it into a community center. If they did that, they could close the 100 block, but unless the post office and Kum n Go moves they won't close the 200 block.
I'd settle for the 100 block. Either make the fire station entrance on Chamberlain or move it somewhere more accessable. Honestly, it just makes too much sense...imagine Campustown without the parallel parking. Wider sidewalks with outdoor tables in front of restaurants and bars. That would be a major improvement.
