A few things here;
How do you know the school has not seen him or someone they rely on has not seen your son play?
Why does distance matter where he attends college? The boy should go where he wants to go for his needs not yours--my guy went 2000 miles away--he was overjoyed to be there--I didn't get to one game but missed none on the radio--We never had distance enter the picture during recruiting
It is not the end of the game if the boy does not attend junior day---in this economy the coach and his staff can certainly undertsand why at this point in time it is not feasible to be there---if he cannot attend have the boy phone them and say thanx for the invite and explain why he cannot be there
