That may be the least of the problems for the extension, however, as a clear horizontal view exposes how much of a slope there is to the extension as it proceeds away from Cafe Kubrick. It may be difficult to see in this photo, but viewed in real life, it's certainly present. Tilt!
It really doesn't pay to underestimate incompetency.
UPDATE, Saturday: A couple of workers bustling in the rain trying to finish up the job now. Fazio Traina, Lawn Sprinklers specialists from Brooklyn, is the company. They also do landscape lighting. I can feel a sense of victory coming up, though the Grand Fissure may still remain so for a better day.
