The grill is coming! The grill is coming!

I've purchased our new gas grill, will pick it up this afternoon, and hope to be eating grilled food tonight! Only one problem (other than the housemate not coming through with the employee's discount) and that is I don't know how to season a grill. I think I have to do that before cooking on the cast iron surface.

Any experienced grill seasoners out there? (I love writing like there's an actual audience of readers...)
