It's an odd feeling to be enveloped in red bricks. The side walks are the same dark terra cotta shade as the buildings, giving a sense at moments of being in a large red room. I've heard the lanes of Mykonos described in this way as well.
The freeze/thaw of winter is over, and the sidewalks still speak of motion. You can see they're not really flat, but shifting in gentle waves. Sometimes a brick will pop out of the grid and simply float there. Often, someone has moved a brick and there it sits, free, but a hazard to walkers.
The South End is beautiful but hospitable only to those who are sharp-eyed and sure of step.
