I also grilled a few ears of corn. This is so easy, I don't know why people make a huge production out of it and it's a great technique because the corn is cooked in the husk, which gives it even more flavor.
Lay the whole ear on a hot fire, husk and all. You can pre-soak but with really fresh corn I don't feel it's necessary, the kernels and the silk should contribute enough moisture to create the steam you need. Keep it turning, removing the husk layer by layer as they burn away. You don't want to do this too early because you'll lose that seal that's keeping the steam in. I keep a plastic bag around for the husks and I just hold the ear with my tongs and pull the husks off by hand. You might want to keep a side towel handy for this if you're not a total masochist like I am...
In around 15 minutes, push on a few kernels. If they feel soft and well, cooked you're about there. Take off the rest of the husk, give the corn a few minutes on the coals to sear off the silk, and enjoy!
