Many people have been — and continue to be — very helpful in my quest to locate seasonal & tourney games won and lost. I appreciate all their help & patience. Alphabetically, many thanks to Steve Dimitry (The Softball History website), Larry Fisher (ISC Fastpitch), Stormy Irwin (historian extraordinaire), Luann Madison (Softball Magazine), Greg Nydick (NY Gremlins), Dan Pfeffer (gosoftball.com), Codi Warren (USA Softball), and Erica Westly (FASTPITCH author).
