Haven't tried wrapping any birds with bacon, seems like a waste of bacon to me. I wrap the end pieces that burn with aluminum foil about half way through though. With beer can chicken I just go with a pale ale, some smashed cloves of garlic and rough chopped rosemary and thyme after rubbing the bird with canola oil then topped with salt and garlic powder. Gives a nice crispy skin with good seasoning.

Been a few years since I made gumbo, would love to see what you found.
