Note:  An alternate method of preparing the corn on the cob in the shucks of which I have done in the past but can't easily locate my archived pixs as follows:  Soak each ear of corn in the shuck for a couple hours and peel the shuck back from each ear of corn leaving the shuck attached to the ear of corn and remove the silk.  Add butter,  salt and freshly ground black peppercorns and place the shuck (outer covering)   back over each  ear of corn on the cob and grill over indirect heat at 350 degrees for 1 1/2 to 2 hours until desired tenderness is reached.  Below pixs of plated grilled steamed corn on the cob prepared on 05-02-09 by Bill aka Mickey Porter:

Today was beautiful with a few clouds rolling in and a great time to fire up the charcoal and gas grill on the deck.  I grilled the Porterhouse steak using charcoal and used the gas grill to prepare the baked potatoes, corn on the cob and onions.  An outstanding meal even if I do say so myself!  See my Grilled Steak recipe.
