Alley Cat Allies is based in Maryland, Baltimore, I beleive. They started teh TNRM programs in an aggressive way, and were able to show that is works. They are now sort of a "parent" organization, helping local groups get organized all over the country. The group I did TNRM with, PawsWatch, is closely affiliated with ACA. ACA sends folks out to give seminars, and I think they also have a legislative branch now.

Here is their web site:
