Things to do this weekend for (mostly) free
Word is, there are going to be up to 2 million people watching the big parade on Saturday, and maybe another 2 million watching the Marathon Sunday, so this would be a terrific weekend to enjoy the wonders of public transportation (parade here, marathon here (pdf)).
The Greenwich Village Halloween Parade Line up in costume on 6th between Spring and Canal 6:30-8:30 to march, or between Spring and 21st after 7 to watch.
