Did a quick search of the web and found the usual.
What I also found was the suggestion to use lemon juice on the skin prior to putting in the smoker. The site was doing this when roasting chickens so we are is the same relative ballpark.
I'm going to give this a shot with lemon jiuce on one and lime juice on another.
Will note how this works unless someone gets the nerve and beats me to it.
Here's a link to the site if you are interested:http://www.theheartofnewengland.com/...stChicken.html
