I've compiled a list of NY and NJ state senators' office phone numbers. I've included the phone numbers for all their offices.

If there are typos, or I find out about additional phone numbers, I'll update on the Gist. And, of course, you can fork it as well. I don't remember if Gists support pull request, but if it does, go ahead. I believe you can comment, at least.
I am working on members of congress for NYC, but there are a lot of them, and you have to know the boundaries of your district to know your rep.
Idea: I would eventually like a git repo containing phone numbers for all senators and members of congress, but there are a 535 of them. Can we get people to collaborate on this?
