I've done corn naked (fully husked and silk removed, no re wrapping), partially husked and silk removed, and completely wrapped up. All work. I like the corn to get a little charred so a lot of times I go naked. I also don't cook it that long. Good, fresh sweet corn doesn't need much cooking. I like it a little crisp still.
No offense to the seafood boil folks, but good summer corn boiled for hours in salty water doesn't do it for me.
