It seems that many people have visited this blog in the past few days by trying to find out how they can help. NYC Sandy Needs has a ton of information for New York and New Jersey. This blog has a good list of resources. The Occupy Sandy twitter account is good for updates. A friend of mine who works in social services posted this on facebook the other day:
All: if you want to help, Coney Island is in desperate need of help. Walked up and down the streets and went door to door. People are in real bad shape. Found a couple w/ a 20 day old baby wrapped in blankets. No heat/electricity, formula or diapers. Went and bought them formula & diapers and will return to bring them coats. Please go out and just knock on doors. Give out coffee. Food. Anything!
Hope this is useful!
