It's true that NYC street street data could use refinement, but I
supsect that we may get NYC data for that in the not-too-distant future.
On the other hand, there's a wealth of information that we could collect.
I was thinking of maybe an event with the NYC Wikipedians, as they're
having an event looking for historical sites and monuments:
The local community did an event for it last week, but I was at State of
the Map and didn't know about it until it was too late, but maybe we can
do something now.
