Gotcha. My sister (who is 43) played amateur softball in MA which I guess was some sort of precursor to TB. She played local teams from nearby towns but then ended up playing in some National tournament in Oklahoma (hey go figure) at the end of the year..may have been an ASA national tournament in Tulsa? She didn't play softball in college, but probably could have (probably D2). Instead she chose to play D1, albeit small conference (Patriot leage), volleyball.
In the early 1990s, women's fastpitch was played, more or less, only in Arizona, West Texas, SoCal, Chicagoland and Massachusetts. Other than U So.Carolina and Louisiana Lafayette, the southeast was a huge softball wasteland.
Oklahoma was (and is) the HQ of ASA softball. ASA softball was literally the only game in town until the mid 1990s. There was only one national fastpitch softball tournament...the ASA tournament.
