They're scattered about that's for sure. There are a few listed here, but I would also check the US Scanning mailing lists link to see if we have a Yahoo group for your area listed;

Of course, you should also check the various PRO96 Yahoo groups (listed on that wiki article). Don't ignore the Win96 Yahoo group - even if it doesn't have a file for your area, it's very likely someone does have it there, assuming you didn't request one in whatever state's forum you live in.
Get a premium subscription and you can use the database to fill in the freqs and talkgroups from the database using the web service. The very first article in the wiki has the links.
