Got a feeling we are going to talk about zinc poisoning again. Some feel that galvanized metal is dangerous for cooking, others don't.
When you set up your trash can cooker, what is the heat source? Do you have a fire or something in the bottom of the can, and put the lid on, or what?
I don't have a strong opinion one way or the other about the zinc issue. I'm mostly just curious about your set up.

Not being a metalurgist, I can't actually address the dangers one way or the other, but my understanding is that to use galvanized you need to burn off whatever it is that's dangerous. We've been doing it a while and no one has had any adverse reaction (yet).
Set up is simple (has to be for me). I use a rack designed for this type of roasting but you can drive a stake in the ground and put the turkey on it. Stake needs to be high enough to keep the bird off the ground but low enough that it doesn't touch the can when you put it over the bird.
Heat source is charcoal. Once I get the coals started I place them the entire way around the outside bottom (which is actually the top of an upsidedown can) and cover the top with a
single layer of coals. This is not a smoker and there are no coals inside with the bird. If you have too much heat on the top you might scorch the top end of the bird (experience talkin' here). As the coals turn to ash you will need to add more. My rule of thumb is
about 45 - 60 minutes for each 5 lbs.
Basically, convection cooking in its simplest form.
BE FOREWARNED: If you do this in the yard you will have something resembling a 'crop circle'!
