I coached middle school football in the early 80's in Columbus, IN. I can tell you that my black players were terrified when we played in Martinsville, and I had to make sure that they always were with a group when going to the bathroom or whatever. At that level, there was no monitoring what the teams did. At the high school level, with state rankings and media coverage, this wasn't a problem.
Glad to hear that things have changed there. Sorry it took so long though.
