Good feedback in previous posts!
It could be said there is no such thing as sending out too many emails!
Even if they are going to a college who's not attending you are still letting a college know there's a softball player interested!
Btw, sometimes colleges are saying they will show up and you may never see them. Sometimes it happens they do show up but it's like a Sasquatch sighting. They're not always going to be sitting there making their presence known.
I saw the Michigan coaching staff at the Sparkler last summer in a Subway getting lunch. Never did see them at the fields.
