I do believe Francis7's son attended a northeast program where this occurred. So it's just not in the south or midwest where this is occurring.
On a college campus you may find many different organizations that welcome students to join, on their own, not try to force their beliefs by going after the student or athlete.
I have friends where this has occurred about mandatory meetings, bible study and were never informed about it before they enrolled or mentioned by the coach. It is happening everywhere.
