Some info concerning Texas here ...
Regarding the participating teams in the Coral Gables regional ... we may have the only regional where every team has competed at the College World Series ... and since the 1986 season as well (not like someone played in 1947 and has not been back since). In fact, each team has placed at least third at the CWS.
Many folks do not remember, but Maine was a mainstay at the CWS in the 80's ... competing there for four consecutive years ('81 -> '84) as well as 1986. The Black Bears have made the CWS seven times in their history.
On a fun note ... a few years ago when I was staying at Disney's Beach Club Villas and hanging out at the pool, I ran into a former Maine ball player who recognized my Ragin' Cajun baseball cap and was very complimentary of the Cajun baseball program. We talked baseball for a while ... and discussed his time at the CWS in the early 80's. If I remember correctly he hit in the 5 and 6 spots. He was coached by the legendary John Winkin.
