Smokefred,this past Monday I put a big Butt in my Fridge in the garage and forgot to turn it down,it was set to 38*f and didn't thaw,so Wed when I went to Smoke it -frozen in the - well all the way about it.I had already got my coal bed set and Smoker up to temp. when I realized this,I put it in the Smoker @225*f(well above safe temps.) and let her go.
Didn't hurt a thing , took it to the clubhouse and they loved it;as forloveofsmoke said,nothing touching and Birds allways on bottom.
Have fun and,
