Hello all. New to the boards and need a little help..

I have a son, who is 16. He has been boxing golden gloves and wrestling (Free and Folkstyle) since age 8. Has also received his blue belt in BJJ and has been training Muay Thai for almost a year.
He is getting "somewhat" bored with just boxing and wrestling matches.
We live in Tennessee and Adult MMA was just made legal in July of '08. Youth MMA is still illegal.
My question is, Does anyone know where it is legal and how could I get him involved?

Thank You..
