Hi, thanks to xing and roberto I've figured out all the collision detection, but Im running into 1 small problem.   I just probably need to stop messing with rad for a little.  I've been none stop since I grabbed it.  Anyways....

Setting a dynamic rigidbody to -1 makes my tunnel obviously detected by collision, but I want to be able to go through the tunnel and yet still hit the sides.

Thanks for any help guys.
