Somtimes you get the bear, and sometimes the bear gets you!

Well this time my BIL got the bear and he wants me to cook a roast. Now I've found a few recipes for stews and steaks and such but I need a recipe more suited to a roast on a smoker cooker. Specifically, what temps do I need to get the roast to for safety sake without overdoing it. Any suggestions out there? (I know this is a rhetorical question since no one reads this blog except for maybe my wife, and that's only if I remind her it even exists. But as I said in my second post, I'm just doing this for the practice!)
