I've enjoyed you guys' thread! My husband tried low carb but somehow didn't get the success that other people have had. Oh well. I subscribe to the theory of eat what you want (just not mountains of it), and burn it off. You enjoy life so much more that way.
I wish I had a smoker of my own! 
Best wishes with the upcoming wedding, Big Dog.
Well, Karin, you really don't need a smoker. Do you have a grill? Doesn't matter if it is charcoal or gas.
If Charcoal, start your charcoal, and once it is all ready, move it all to one side. Place meat on the "indirect" heat side. Buy wood chips at Lowes, and soak them as per directions. Sprinkle a few over hot coals. Add new chips when smoke subsides a bit. Kinda tedious, but works well.
Or, for gas or charcoal, you can buy a "smoker box" that you fill with wood, and place over burners on the gas grill, or over direct heat on the charcoal grill.
Or, if you are cheap, like me, get some heavy duty tin foil, and double wrap the wood chips and cut slits in the top, and treat it like a smoker box.
Sure, I wouldn't try a brisket for 12-16 hours, but some ribs for a few hours, would be good. Most of the time, you only smoke about half the time, and wrap with foil, and cook until done. So, smoking a Boston Butt for 4 hours wouldn't be too bad. Try it, and I am sure you will be amazed what you can do.
