Share 'Smoker Fuel'

Well, I've run out of sunflower heads and stalks from my yard I've used for smoker fuel.  There's a good crop coming in this year, so I should be good for next year.  Does anyone have a good source of smoker fuel here in town, or would be willing to sell me a 5 gallon bucket's worth?  That should carry me through the rest of the year.
