Some of you were talking about BBQing in the winter: my winter solution is to set up the grill inside my woodstove! We have one of those cheap portable grills, and we just stick the whole thing inside the woodstove and light the charcoals. Works great, no smoke, nice & cozy inside the house. Great solution for cold days, rainy days, mosquito-season, whatever. I imagine it would work well in a fireplace too.

Note: I wouldn't recommend cooking over burning logs, unless you are familiar with wood types. We tried this once, and the food tasted horribly like the wood, not a good flavor--don't know what kind of wood it was.
