whats the best way to smoke some sweet corn in the husk

Personally I've never tried cooking corn like that on my smoker, but I have had good luck cooking it on my gas grill. All I do is soak the corn in water for at least half an hour and then cook it in med-high heat on a heating basket for about 40 minutes. Make sure to keep it rotated every 10 minutes or so to cook it evenly. Then pull it off and as soon as its cooled down enough to handle, just pull off the corn silk and shuck it. You'll end up with a nice roasted corn flavor.

Wouldn't it be easier to remove the silk before roasting?

Yes it is, I pull back the husk, remove the silk, pull the husk back up twisting the ends and put on the grill. I usually melt some butter adding chili powder or texmex seasoning and brush it on also.
