Take a look at this: This is my brother during a recent jam session we had. Notice the kerosene heater? That's the only heat we have in the room where my drumkit and his amp are. The heater's been getting a lot of use lately, but fortunately at the time this pic was taken, it was warm enough in there that we didn't need it (notice no glow from the window of it, meaning's it's off). So, what kind of heating do you other drummers have so you can play this winter without freezing to death?
