I have adjusted my polygon-checker-script to handle the delorme challenge for NY as well:
http://project-gc.com/Challenges/GC102CP/1839
Right now, it is not possible to specify the polygons in a tag since they are so big. They have to be inserted into the script, so to create new checkers for other delorme challenges, one has to either clone the whole script or ask me to do it (I prefer the later until there is a possibility to specify the polygons in the config). It is also some work to get the polygons, but I have the process automnated, so it doesn't take very long.
