I just ordered the ole smokey electric smoker. It had the best reviews of all the ones I could find. I am charcoal man and I know electric smokers are sacrilege, but with my schedule I don't have time for charcoal most days. My question- this smoker has a tray for wood chips to generate smoke anf I have no idea where to get them. Thought about just using some of my firewood split into small pieces, but don't want burn my deck down
