You probably don’t have to, but I would definitely throw bear in the oven after smoking unless you put a couple of thermometers inside the smoker so you at least know the time/temp it was cooked at. There are some cheap dial thermometers out there that you could at least put above the top shelf where it’s the coldest. You’ll probably want to rotate the racks as well, because the bottom rack tends to cook faster.

You might find that smoking them to fully cooked is too smoky and you might decide to do 45-60 mins smoke and finish it off in the oven.
