This is what I use:
At home using a garbage can smoker: Beef:mesquite, maple, oak. Pork: Hickory, apple Chicken: apple, maple, oak and sometimes mesquite. Fish: apple, maple. Jerky: mesquite only.
At home on the charcoal grill: I stick with pretty much the same woods as above with the exception of using cedar planks for fish. And I don't make jerky on the grill.
When car camping:I'll bring along some maple or oak logs.
Dinosaur: I'm kinda curious about using willow...I may have to try it. Can ya recommend a meat that goes good with it?
