I also did a dry run for Thanksgiving with the PBC turkey hanger.
I had a 12.5 lb bird. It took a good bit longer than I was anticipating, at almost 6 hours.
It was on the cold side and quite windy. It was so windy I actually went out and made a wind break for it after a few hours.
It's three panels of 1/2" plywood, 2 ft wide and 38" tall. They are hinged so that it folds flat. I have a fourth piece I use as a roof.
Anyway, back to the turkey: it came out fantastic. We invited the neighbors over and had a little feast. They raved about the bird.
