News to me that you can't photograph private property... depends on the
kinda private property George wanted to hide I guess. Though I do know
that images of icons, such as the Chrysler Building, may be vigorously
defended. Though it seems to me a really odd situation these days where
you can't get away with taking whatever photographs you want... though I
remember last time I had a problem was with Tibetan long horns in the
Houston art museum. But I don't think that was private property.

These two would be joints where concrete is separated... that the slabs
are not in contact with each other.
I have not yet figured out why anyone thinks caulk does diddly in a
sidewalk joint.
I have certainly installed plenty of them just can't imagine why it
makes any difference.
We used every few years to have to caulk the expansion joints in a
swimming pool on the North Shore of Lung Island w/ a bottom that had
been built below sea level. That was a pain in the ass. Caulking to the
tides. JP Morgan's golf club... I don't think they like me any more
since the new company did not honor the efup of the old company, which
is fine by me.

Go to Home Depot and if you are lucky you can find this stuff in the
concrete materials area. As to the installer nobody cares if it sticks
up and gets abraded.

Where are these located in relation to the others? According to the
Occam's Razor Law no effort should be expended in any project that is
not absolutely required so I am wondering if this extra step does not
represent an early caught F up of some sort.

But these sawn joints are left unfilled (work was finished a week
ago). Won't they allow water in and thus freeze-thaw damage? Or, the
work being done in May, the contractor (who is, in my experience, unique
in making these saw cuts) counting on fillage by dog shit, grit, spittle
and other sidewalk depositions?
I would vote that they are not counting on anything. Not even counting
on dog shit.
