Hard to believe I've never grilled corn, but last week I gave it a shot. It tasted exactly like it tasted the night before when i boiled it, but when i grilled it I felt really really manly, so it's kinda worth it. Here's what i did:

• Pull down the husks leaving them attached
• Remove the silk
• Pull the husks back up and tie with some twine
• Soak in water for 10 minutes
• Toss 'em over some medium hot coals, and cook or 15 minutes, rotating every 3-4 minutes. 
• Discard husks, and eat
